The package management story in Haskell, I don't want to say broken, is just too complicated for beginners, err actually everyone. For instance, to install stylish-haskell you will ultimately need the "happy" executable, but cabal is not smart enough to get it for you. I don't know what a "clean" environment means, nor do I know what you mean by "broken dependencies." Did you: mkdir stylish-sandbox cd stylish-sandbox cabal update cabal sandbox init cabal install happy stylish-haskell cabal copy cd .. rm -r stylish-sandbox That might work.
