Hi Peder, I'd recommend giving stack a try (https://github.com/commercialhaskell/stack). I have found it easier to use than cabal-install. Many executables will install just fine using `stack install <package-name>`. Packages that stack has trouble creating a build plan for (like hakyll) can usually be installed using the following: stack unpack hakyll cd hakyll-* stack init stack setup stack install `stack install` copies the resulting binaries to ~/.local/bin by default: add that to your path. Cheers, cydparser

Hi,

Been with Haskell just for few days, and thought it would be a good exercise to run a static site generator to get familiar with various tools, and I?m already running into ?cabal hell? I think. :(

$ cabal install hakyll Resolving dependencies... cabal: Could not resolve dependencies: trying: hakyll-4.7.2.0 (user goal) next goal: time (dependency of hakyll-4.7.2.0) rejecting: time-1.4.2/installed-d67...

Backjump limit reached (change with --max-backjumps).

I?m running OS X Yosemite 10.2.2 with all the latest versions of Haskell and cabal.

Thanks you for listening. :)
