Of course, when I last tried installing stylish-haskell (last week), it insisted on taking non-compatible/broken dependencies. Yes, on a clean environment. When I learn more Haskell, I may succeed to figuring out what's wrong.

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.

  so, what does `cabal copy` do? copy the sandbox to your local .cabal/bin/?

    yeah

      Doesn't do it. In other news, stylish-haskell appears to have been updated and now installs. :) Still, as a first experience of haskell, it ain't great.

Don't blame Haskell for it. On Gentoo with the official 'haskell' overlay it's just a matter of running emerge stylish-haskell
