Thanks! No problem. I gave a try to your suggestion. It doesn't look I'll get yesod installed without "paying" a bigger price than just "downgrading". :-/ Yesod 1.4.0 warns that forcing installing it will likely break pandoc, among other things. I can give it a try though, but I really use pandoc regularly. Plus, it's still not clear that the building process will not fail. And installing pandoc took me surprisingly a lot of time last time. Forcing Yesod-1.2.6.1 won't allow cabal to satisfy the dependencies. I guess I could keep trying other versions and see. But I think I'll try the 1.4.0 first. Will post here the results so that at least others may hopefully benefit from this. ----------------------------------------------------------------------------------------- msantos@MBP-2[15:42]:~/System$cabal install yesod-1.4.0 Resolving dependencies...

I haven't yet read how to use sandboxes, so, no, that I tried just like that cabal install... I did check first that cabal info yesod was saying I didn't have it install. But now that you mention it, I did may have had other packages lingering around from my last attempt of installing yesod. Meanwhile I did run forcing the install of 1.4.0... Ah, it finished with cabal install --force-reinstalls yesod-1.4.0 and... it complains about the shakespeare. "shakespeare-2.0.5 failed during the building phase.

Some of that looks like churn from trying to install an older version of Yesod over a newer one. Are you using a sandbox? if so, did you wipe it out before attempting Yesod 1.2.6.1? What we'd be looking for is a package conflict that tells you which package of what version that is globally installed is causing the conflict.

Insta-Yesodian conflict implies you're reinstalling into a not-fresh packgage-db which means you either need to wipe your user package-db or use a sandbox. (I recommend the latter).

If you haven't done so, do that, then re-attempt that version of Yesod (1.2.6.1).

Thanks! No problem. I gave a try to your suggestion. It doesn't look I'll get yesod installed without "paying" a bigger price than just "downgrading". :-/

Yesod 1.4.0 warns that forcing installing it will likely break pandoc, among other things. I can give it a try though, but I really use pandoc regularly. Plus, it's still not clear that the building process will not fail. And installing pandoc took me surprisingly a lot of time last time.

Forcing Yesod-1.2.6.1 won't allow cabal to satisfy the dependencies.

I guess I could keep trying other versions and see. But I think I'll try the 1.4.0 first. Will post here the results so that at least others may hopefully benefit from this.

Ah that's frustrating, that's my mistake – I'm sorry. I thought you were talking about GHC for Mac OS X not being available for your OS version either.

Your best bet on HP is to specify an older version of Yesod that will work with the dependencies that your version of HP comes with.

Did you see that the Mac instructions said to follow the "other *nix" instructions if you were using an older version of Mac OS X?

Those link here: https://www.haskell.org/ghc/download_ghc_7_8_4#binaries

Get rid of all that (GHC, HP, Cabal), then install GHC using the bindist for Mac OS X linked above.

Hmm.. wouldn't that mean, I later have to reinstall all my packages? :-/ Meanwhile, I did try the sandbox way. It didn't work either. Briefly I issued cabal sandbox init and then cabal install yesod-1.2.6.1 Details below.

I haven't yet read how to use sandboxes, so, no, that I tried just like that cabal install... I did check first that cabal info yesod was saying I didn't have it install. But now that you mention it, I did may have had other packages lingering around from my last attempt of installing yesod.

Meanwhile I did run forcing the install of 1.4.0... Ah, it finished with cabal install --force-reinstalls yesod-1.4.0 and... it complains about the shakespeare.

"shakespeare-2.0.5 failed during the building phase. The exception was: ExitFailure 1"

I'll give a try to the sandbox solution.

Some of that looks like churn from trying to install an older version of Yesod over a newer one. Are you using a sandbox? if so, did you wipe it out before attempting Yesod 1.2.6.1? What we'd be looking for is a package conflict that tells you which package of what version that is globally installed is causing the conflict.

Insta-Yesodian conflict implies you're reinstalling into a not-fresh packgage-db which means you either need to wipe your user package-db or use a sandbox. (I recommend the latter).

If you haven't done so, do that, then re-attempt that version of Yesod (1.2.6.1).

Thanks! No problem. I gave a try to your suggestion. It doesn't look I'll get yesod installed without "paying" a bigger price than just "downgrading". :-/

Yesod 1.4.0 warns that forcing installing it will likely break pandoc, among other things. I can give it a try though, but I really use pandoc regularly. Plus, it's still not clear that the building process will not fail. And installing pandoc took me surprisingly a lot of time last time.

Forcing Yesod-1.2.6.1 won't allow cabal to satisfy the dependencies.

I guess I could keep trying other versions and see. But I think I'll try the 1.4.0 first. Will post here the results so that at least others may hopefully benefit from this.

Ah that's frustrating, that's my mistake – I'm sorry. I thought you were talking about GHC for Mac OS X not being available for your OS version either.

Your best bet on HP is to specify an older version of Yesod that will work with the dependencies that your version of HP comes with.

You don't need to rm -rf ~/.ghc if you're using a sandbox. The sandbox (usually) occludes the user package-db. Well, the sandbox may not have fixed the incompatibility of HP and that particular version of Yesod, but we're better information from the dependency solver. That said, this is going to simply require a lot of trial and error if you want to try this approach and me telling you increment/decrement versions isn't going to be any faster. I'd say your best options are: 1. Upgrade your installation of Mac OS X so you can use the vanilla GHC bindist, or even better, GHC for Mac OS X 2. Use your copy of Haskell Platform to build GHC from source and use that instead of GHC (possibly a quagmire, might work out okay. Will take a long time to build.) 3. Unregister all the unnecessary packages from your global package-db. Listing here: https://www.haskell.org/platform/changelog.html (Additional Platform Libraries, do *not* uninstall any of the core libraries) If you make a mistake you may need to reinstall Platform. 4. Give passing --allow-newer to cabal install a shot. This is rough. Not that many people on <10.7 OS X versions so there aren't enough squeaky wheels for this sort of thing. Sorry I couldn't do more.

Meanwhile, I did try the sandbox way. It didn't work either. Briefly I issued cabal sandbox init and then cabal install yesod-1.2.6.1 Details below.

The initial complain about not being able to resolve dependencies makes me think I may be missing more things about working with sandboxes. Just checked

https://www.haskell.org/cabal/users-guide/installing-packages.html#developin... and guessed the init would be enough.

I haven't yet read how to use sandboxes, so, no, that I tried just like that cabal install... I did check first that cabal info yesod was saying I didn't have it install. But now that you mention it, I did may have had other packages lingering around from my last attempt of installing yesod.

Meanwhile I did run forcing the install of 1.4.0... Ah, it finished with cabal install --force-reinstalls yesod-1.4.0 and... it complains about the shakespeare.

"shakespeare-2.0.5 failed during the building phase. The exception was: ExitFailure 1"

Below the full output.

I'll give a try to the sandbox solution.

Some of that looks like churn from trying to install an older version of Yesod over a newer one. Are you using a sandbox? if so, did you wipe it out before attempting Yesod 1.2.6.1? What we'd be looking for is a package conflict that tells you which package of what version that is globally installed is causing the conflict.

Insta-Yesodian conflict implies you're reinstalling into a not-fresh packgage-db which means you either need to wipe your user package-db or use a sandbox. (I recommend the latter).

If you haven't done so, do that, then re-attempt that version of Yesod (1.2.6.1).

Thanks! No problem. I gave a try to your suggestion. It doesn't look I'll get yesod installed without "paying" a bigger price than just "downgrading". :-/

Yesod 1.4.0 warns that forcing installing it will likely break pandoc, among other things. I can give it a try though, but I really use pandoc regularly. Plus, it's still not clear that the building process will not fail. And installing pandoc took me surprisingly a lot of time last time.

Forcing Yesod-1.2.6.1 won't allow cabal to satisfy the dependencies.

I guess I could keep trying other versions and see. But I think I'll try the 1.4.0 first. Will post here the results so that at least others may hopefully benefit from this.

Ah that's frustrating, that's my mistake – I'm sorry. I thought you were talking about GHC for Mac OS X not being available for your OS version either.

Your best bet on HP is to specify an older version of Yesod that will work with the dependencies that your version of HP comes with.

One more detail about my try with rm ~/.ghc: I find it curious that I didn't get that directory rebuild again when trying to install yesod.

Ok, removing ~/.ghc (actually just moving it to ~/.ghc-org) didn't work either. The detailed output is below but from a cursory view it seems not much better than within the sandbox try before.

I understand I'm staying in the "past" and with that comes problems like this one, but upgrading to Yellowstone is not an option for me.

I have some questions about your other options. In particular, I'm not sure what you mean by (capitals) GHC. I thought that's just the compiler. I don't understand your first sentence after "vanilla". What is what I got with HP if not GHC for MacOSX!?

About point 2., I'm building (already for hours, that's the 'other' process I'd running) ghc from the tarball ghc-7.8.4-src.tar.bz2 available at the bottom of that same link we mentioned before, namely, https://www.haskell.org/ghc/download_ghc_7_8_4#binaries Is this the same as what you mean by this 2nd option? Mind you I'm already using version 7.8.3. How will a new version of the compiler change what looks like a compatibility problem with a package? or you mean it is not that simple?

Option 3: It seems to me I may as well just remove everything, install HP again (already downloaded) and after that step finishes, trying installing right away yesod, before I try with any other packages. Seems a path based mostly on blind hope than logic to me :-p as the only big thing I installed between my fresh install of HP and my initial try of yesod was pandoc, which had some large dependencies to deal with. But it's a simple one, so I may check it definitely out of the equation.

Option 4: I guess this is something I can try right away without much effort. To be concrete you mean then cabal install --allow-newer yesod ?

Btw, thanks so much for your prompt help!

You don't need to rm -rf ~/.ghc if you're using a sandbox. The sandbox (usually) occludes the user package-db.

Well, the sandbox may not have fixed the incompatibility of HP and that particular version of Yesod, but we're better information from the dependency solver.

That said, this is going to simply require a lot of trial and error if you want to try this approach and me telling you increment/decrement versions isn't going to be any faster.

I'd say your best options are:

1. Upgrade your installation of Mac OS X so you can use the vanilla GHC bindist, or even better, GHC for Mac OS X

2. Use your copy of Haskell Platform to build GHC from source and use that instead of GHC (possibly a quagmire, might work out okay. Will take a long time to build.)

3. Unregister all the unnecessary packages from your global package-db. Listing here: https://www.haskell.org/platform/changelog.html (Additional Platform Libraries, do *not* uninstall any of the core libraries) If you make a mistake you may need to reinstall Platform.

4. Give passing --allow-newer to cabal install a shot.

This is rough. Not that many people on <10.7 OS X versions so there aren't enough squeaky wheels for this sort of thing.

Sorry I couldn't do more.

Some of that looks like churn from trying to install an older version of Yesod over a newer one. Are you using a sandbox? if so, did you wipe it out before attempting Yesod 1.2.6.1? What we'd be looking for is a package conflict that tells you which package of what version that is globally installed is causing the conflict.

Insta-Yesodian conflict implies you're reinstalling into a not-fresh packgage-db which means you either need to wipe your user package-db or use a sandbox. (I recommend the latter).

If you haven't done so, do that, then re-attempt that version of Yesod (1.2.6.1).

Hi, I think Stackage will solve these issues - indeed, I believe that Stackage grew out of the difficulty of installing Yesod and its dependencies straight from Hackage using cabal. If you download https://www.stackage.org/lts/cabal.config next to your own .cabal file then it will constrain cabal to only use a set of packages which are known to be mutually compatible. Hope that helps, David On 19 June 2015 at 08:37, Geraldus <heraldhoi@gmail.com> wrote:

Hi, Miguel. Haskell Platform includes GHC itself and some set of packages, such as text, network, and etc. If I recall correctly thete was issues with Yesod and HP because some package versions and the best way to install Yesod were sandboxes, because sandbox have its own package database. Removing or just moving .ghc folder helped me in past several times, usually it was needed when different projects depends on different package versions, now I put every project inside sandbox to prevent this. As for pandoc, if you use only binary you can install it having no GHC at all (download package installer from website). If I were you I'll install GHC 7.8.* alone rather than Platform, caball-install 1.22.* and try to build everything againg using sandboxes. Also there is a Stackage and its tools (stackage-cli and recently released stack), they are very helpful in caball-hell issues. Also there is Halcyon but I have not tried it myself. Apologize for missing links, I'm mobile now.

One more detail about my try with rm ~/.ghc: I find it curious that I didn't get that directory rebuild again when trying to install yesod. Did I miss something?

Ok, removing ~/.ghc (actually just moving it to ~/.ghc-org) didn't work either. The detailed output is below but from a cursory view it seems not much better than within the sandbox try before.

I understand I'm staying in the "past" and with that comes problems like this one, but upgrading to Yellowstone is not an option for me.

I have some questions about your other options. In particular, I'm not sure what you mean by (capitals) GHC. I thought that's just the compiler. I don't understand your first sentence after "vanilla". What is what I got with HP if not GHC for MacOSX!?

About point 2., I'm building (already for hours, that's the 'other' process I'd running) ghc from the tarball ghc-7.8.4-src.tar.bz2 available at the bottom of that same link we mentioned before, namely, https://www.haskell.org/ghc/download_ghc_7_8_4#binaries Is this the same as what you mean by this 2nd option? Mind you I'm already using version 7.8.3. How will a new version of the compiler change what looks like a compatibility problem with a package? or you mean it is not that simple?

Option 3: It seems to me I may as well just remove everything, install HP again (already downloaded) and after that step finishes, trying installing right away yesod, before I try with any other packages. Seems a path based mostly on blind hope than logic to me :-p as the only big thing I installed between my fresh install of HP and my initial try of yesod was pandoc, which had some large dependencies to deal with. But it's a simple one, so I may check it definitely out of the equation.

Option 4: I guess this is something I can try right away without much effort. To be concrete you mean then cabal install --allow-newer yesod ?

Btw, thanks so much for your prompt help!

You don't need to rm -rf ~/.ghc if you're using a sandbox. The sandbox (usually) occludes the user package-db.

Well, the sandbox may not have fixed the incompatibility of HP and that particular version of Yesod, but we're better information from the dependency solver.

That said, this is going to simply require a lot of trial and error if you want to try this approach and me telling you increment/decrement versions isn't going to be any faster.

I'd say your best options are:

1. Upgrade your installation of Mac OS X so you can use the vanilla GHC bindist, or even better, GHC for Mac OS X

2. Use your copy of Haskell Platform to build GHC from source and use that instead of GHC (possibly a quagmire, might work out okay. Will take a long time to build.)

3. Unregister all the unnecessary packages from your global package-db. Listing here: https://www.haskell.org/platform/changelog.html (Additional Platform Libraries, do *not* uninstall any of the core libraries) If you make a mistake you may need to reinstall Platform.

4. Give passing --allow-newer to cabal install a shot.

This is rough. Not that many people on <10.7 OS X versions so there aren't enough squeaky wheels for this sort of thing.

Sorry I couldn't do more.

Hmm.. wouldn't that mean, I later have to reinstall all my packages? :-/

Meanwhile, I did try the sandbox way. It didn't work either. Briefly I issued cabal sandbox init and then cabal install yesod-1.2.6.1 Details below.

The initial complain about not being able to resolve dependencies makes me think I may be missing more things about working with sandboxes. Just checked

https://www.haskell.org/cabal/users-guide/installing-packages.html#developin... and guessed the init would be enough.

If you won't use a sandbox, then lets nuke your user package-db and start from scratch:

Christopher, David, Geraldus, first thanks a lot for your help. Feels easier to dedicate so much time troubleshooting this. I will try then Stack and Stackage then. A few more questions though to make sure I understand things right. Yesterday 1) I did mv ~/.ghc ~/.,ghc-org cabal install yesod It didn't work -that's ok- but it didn't recreate ~/.ghc anew. Is that because nothing new (yesod in this case) got installed? or did I miss something? 2)In order to work with/in a sandbox it's enough to do mkdir ~/mySandboxDir cd ~/mySandboxDir cabal sandbox newPackage right? 3)In order to remove all of my HP stuff last time I manually looked for all Haskell stuff in my system and rm-ed it. If you know of any uninstall script that would be nice! ;-) Finally, a thought to share. The site www.haskell.org seems the canonical place to start playing with Haskell, that is, they explicitly recommend HP as the way to go for older macs. Also, yesod site doesn't mention that HP might be the worse place to start with for installing yesod. I think the community there should get to a consensus and make it clearer. That'd especially help newcomers to Haskell -and we can only benefit from that. Again thanks all. I'll post back my results with stack or stackage so the list has a record of my endeavour with haskell+yesod.

Hi,

I think Stackage will solve these issues - indeed, I believe that Stackage grew out of the difficulty of installing Yesod and its dependencies straight from Hackage using cabal.

If you download https://www.stackage.org/lts/cabal.config next to your own .cabal file then it will constrain cabal to only use a set of packages which are known to be mutually compatible.

Hope that helps,

David

Hi, Miguel. Haskell Platform includes GHC itself and some set of packages, such as text, network, and etc. If I recall correctly thete was issues with Yesod and HP because some package versions and the best way to install Yesod were sandboxes, because sandbox have its own package database. Removing or just moving .ghc folder helped me in past several times, usually it was needed when different projects depends on different package versions, now I put every project inside sandbox to prevent this. As for pandoc, if you use only binary you can install it having no GHC at all (download package installer from website). If I were you I'll install GHC 7.8.* alone rather than Platform, caball-install 1.22.* and try to build everything againg using sandboxes. Also there is a Stackage and its tools (stackage-cli and recently released stack), they are very helpful in caball-hell issues. Also there is Halcyon but I have not tried it myself. Apologize for missing links, I'm mobile now.

One more detail about my try with rm ~/.ghc: I find it curious that I didn't get that directory rebuild again when trying to install yesod. Did I miss something?

either. The detailed output is below but from a cursory view it seems not much better than within the sandbox try before.

I understand I'm staying in the "past" and with that comes problems like this one, but upgrading to Yellowstone is not an option for me.

I have some questions about your other options. In particular, I'm not sure what you mean by (capitals) GHC. I thought that's just the compiler. I don't understand your first sentence after "vanilla". What is what I got with HP if not GHC for MacOSX!?

About point 2., I'm building (already for hours, that's the 'other' process I'd running) ghc from the tarball ghc-7.8.4-src.tar.bz2 available at the bottom of that same link we mentioned before, namely, https://www.haskell.org/ghc/download_ghc_7_8_4#binaries Is this the same as what you mean by this 2nd option? Mind you I'm already using version 7.8.3. How will a new version of the compiler change what looks like a compatibility problem with a package? or you mean it is not that simple?

Option 3: It seems to me I may as well just remove everything, install HP again (already downloaded) and after that step finishes, trying installing right away yesod, before I try with any other packages. Seems a path based mostly on blind hope than logic to me :-p as the only big thing I installed between my fresh install of HP and my initial try of yesod was pandoc, which had some large dependencies to deal with. But it's a simple one, so I may check it definitely out of the equation.

Option 4: I guess this is something I can try right away without much effort. To be concrete you mean then cabal install --allow-newer yesod ?

Btw, thanks so much for your prompt help!

You don't need to rm -rf ~/.ghc if you're using a sandbox. The

(usually) occludes the user package-db.

Well, the sandbox may not have fixed the incompatibility of HP and that particular version of Yesod, but we're better information from the dependency solver.

That said, this is going to simply require a lot of trial and error if you want to try this approach and me telling you increment/decrement versions isn't going to be any faster.

I'd say your best options are:

1. Upgrade your installation of Mac OS X so you can use the vanilla GHC bindist, or even better, GHC for Mac OS X

2. Use your copy of Haskell Platform to build GHC from source and use that instead of GHC (possibly a quagmire, might work out okay. Will take a long time to build.)

3. Unregister all the unnecessary packages from your global package-db. Listing here: https://www.haskell.org/platform/changelog.html (Additional Platform Libraries, do *not* uninstall any of the core libraries) If you make a mistake you may need to reinstall Platform.

4. Give passing --allow-newer to cabal install a shot.

This is rough. Not that many people on <10.7 OS X versions so there aren't enough squeaky wheels for this sort of thing.

Sorry I couldn't do more.

HP 2014.2.0.0 for Mac OS X is built with a bindist of GHC 7.8.3 that *is* compiled with support for 10.6. To remove HP from a system, you can use the handy unisntall-hs command - that does a better job than just poking around by hand. There does appear to be a problem with Template Haskell, and loading some packages that depend on yet other packages to be loaded... For some reason dynamic loading in this case doesn't resolve. Fortunately there is a workaround: ​When you see a message like: Loading package parsec-3.1.5 ... <command line>: can't load .so/.DLL for: /Library/Haskell/ghc-7.8.3-x86_64/lib/parsec-3.1.5/ libHSparsec-3.1.5-ghc7.8.3.dylib (dlopen(/Library/Haskell/ghc- 7.8.3-x86_64/lib/parsec-3.1.5/libHSparsec-3.1.5-ghc7.8.3.dylib, 9): *Library not loaded: @rpath/libHStext-1.1.0.0-ghc7.**8.3.dylib* Referenced from: /Library/Haskell/ghc-7.8.3-x86_64/lib/parsec-3.1.5/ libHSparsec-3.1.5-ghc7.8.3.dylib Reason: image not found) Look at the part in red. It indicates that *text *can't be loaded. You need to add it's libdir to an export like so (you are adding the location of the libHStext... file, which is always in a similarly named directory under /Library/Haskell/ghc-7.8.3-x86_64/lib): export DYLD_FALLBACK_LIBRARY_PATH=/Library/Haskell/ghc- 7.8.3-x86_64/lib/text-1.1.0.0:$DYLD_FALLBACK_LIBRARY_PATH Rebuild, and you may see another to add, and you'll have to do this again. To build shaekespeare-2.0.4.1 on a stock HP 2014.2.0.0 install, I needed to add the following libs to that path primitive, hashable, mtl, and text. I don't yet know if this is a bug in the way the HP libs were built, the way GHC was built, or just a fundamental problem of GHC 7.8.3 (and later) and OS X 10.6. - Mark

Hi, sorry for the late reply. I got Yesod installed and running on my OSX 10.6.8! Before I comment how I did it, let me start again by thanking you all for that quick & generous help. I haven't had the time to try all those different suggestions you all provided although I'd like to do so and post the results here if time permits. It seems to me it could be worth to have a record of it as others may follow a different choice of these approaches when it comes to installing&using Haskell -although that's more of wild guess of mine than an educated one. I tried again the minimal disruptive approach, that is, keep my HP installation and try sandboxing yesod. The quickstart from the yesod site http://www.yesodweb.com/page/quickstart wouldn't work as I said at the beginning of this thread because the shakespeare package didn't get built. That's because those steps suggest installing yesod-bin globally and only afterwards start the sandbox. Reversing those steps does the work. More concretely, what I did was mkdir yesod cd yesod wget --no-check-certificate https://www.stackage.org/lts/cabal.config cabal update cabal install alex happy (actually I had these already installed) cabal sandbox init cabal install network (see below why) cabal install primitive-0.6 (idem) cabal install yesod-bin And at this point shakespeare built fine and yesod got installed. I went then further and did export PATH=./.cabal-sandbox/bin/:$PATH in order to get yesod running. yesod init --bare cabal install -j --enable-tests --max-backjumps=-1 --reorder-goal (probably not necessary; followed blindly init's suggestion) cabal install --run-tests yesod devel That lead to a minor configuring of FirstWebServer-0.0.0..., which triggered a recompile of a few libraries and a rebuild of the application and finally a working Welcome Yesod page at localhost:3000 Trying cabal install yesod-bin right after the sandbox init failed with file not found .cabal-sandbox/logs/network-2.6.2.0.log This required thus to install network. Still yesod-bin install failed again this time complaining about not finding file .cabal-sandbox/logs/primitive-0.6.log, which in turn required the install of primitive-0.6. After that yesod-bin installs without problems. I did do an additional step before the final cabal install yesod-bin, just out of despair of the time devoted to it. That step was a chmod +w .cabal-sandbox/ However, I don't think this is relevant at all. But just in case... Lastly, let me add another suggestion I got from Rahul Muttineni in a private email. As I believe in giving credit where credit is due, I'll paste his answer below for others -and me, in the future- to see. After all I haven't heard of the Nix package manager before. Again, thanks all!. Regards, MA On Fri, Jun 19, 2015 at 11:43 AM, R. Muttineni wrote Hello Miguel, I saw that you had trouble installing yesod on your Mac OS on the haskell-cafe mailing list. I receive the list in digest format, so it's rather cumbersome for me to respond to your thread as it has an extremely long length. For now, I'll respond to you personally. I suggest you try the Nix package manager. I'm currently running both yesod and pandoc on the most recent GHC (7.10.1) with no problems. You can find a tutorial here http://corajr.com/posts/2014/12/22/nix-osx-haskell/. It's very easy. Just write (or generate with cabal2nix) the default.nix file and use the nix command line tools and you're on your way. The packages are built from source so expect it take lots of time. Pandoc will take many hours, but yesod should finish in a couple. If this helped you, please repost this on the mailing list. Don't worry about quoting me, just provide the link for others to see. If you face any issues, feel free to ask me, or you can post it on the nixpkgs github repository and they'll help you out. If you are going to be developing a lot in Haskell, I suggest you invest time in getting to know Nix as it guaranteed to cure cabal hell. Stackage works too, but it doesn't offer you the flexibility of rebuilding the packages for profiling/debugging effortlessly as well as using different versions of the compiler for different packages like it does with Nix. Moreover, nixpkgs currently supports a majority of Hackage, so you don't have to worry about losing out.
