$ cabal update $ cabal install hakyll Resolving dependencies... cabal: dependencies conflict: ghc-6.12.3 requires unix ==2.4.0.2 however unix-2.4.0.2 was excluded because ghc-6.12.3 requires unix ==2.4.1.0 $
Any advice (other than upgrading to 7.0.3, which is not an option at the moment)?
You can run the build with verbose output (--verbose=3) and get more details about why the impossible dependencies were required, or you can build your application (whatever relies on hakyll) with cabal-dev -- I've been able to build hakyll that way on my machine with ghc-6.12.3, so I suspect there is some unexpected dependency in your local package db that is causing cabal to make a series of undesirable version selections. --Rogan
