I didn't get any response on the Leksah forum, so I hope it's ok to ask here.

Sure. Anything Haskell-related is okay to ask here.

First problem, I keep seeing this in the error log:

...

Setup: You need to re-run the 'configure' command. The version of Cabal being used has changed (was Cabal-1.10.2.0, now Cabal-1.10.1.0). Additionally the compiler is different (was ghc-6.12, now ghc-7.0) which is probably the cause of the problem.

When I run configure, it just prints:

...

Resolving dependencies... Configuring pokercalc-0.0.1...

But it doesn't fix anything.

Sorry, no idea for that one.

...

The other problem is when I try to update cabal:

...

cabal install leksah

Resolving dependencies... cabal: cannot configure haddock-2.9.4. It requires ghc >=7.2 && <7.4 There is no available version of ghc that satisfies >=7.2 && <7.4

haddock-2.9.4 is exclusively for ghc-7.2, with ghc-7.0, you need haddock-2.9.2, try

$ cabal install leksah --constraint="haddock < 2.9.4"

...

I'm using Haskell Platform 2011.2.0.1 for Mac OS X 10.6 Any ideas?

I still haven't managed to resolve this. Any thoughts on the errors below?

No idea why binary-shared failed to build. For more info, try to cabal- install it with a higher verbosity level, $ cabal install binary-shared -v2 (perhaps even -v3). The other errors may be cascading from failing to build any gtk2hs package. To install gtk2hs packages, you have to first $ cabal install gtk2hs-buildtools (that package contains only executables, no library, hence can't be a build-depend in the cabal file, alas). If you already have the buildtools somewhere in your path, $ which gtk2hsC2hs would be a quick test, something else has gone awry. Then try to manually install one of the gtk2hs packages, iirc, cairo doesn't depend on any other, so $ cabal install cairo -v2 Hopefully the messages printed to stderr would allow to find out what broke.

I don't understand why packages should be on hackage in the first place if their dependencies are not available from there either. I

Are there packages on hackage with Haskell dependencies not available on hackage? That would be bad. (If C dependencies are not available from hackage, that's inconvenient, but natural.)

feel like you should have to explicitly opt-in to get any package that has non-hackage or unreleased dependencies.

Agreed.
