I suspect the problem is that I haven't emerged dev-haskell/haskell-platform. The Yi documentation at http://haskell.org/haskellwiki/Yi indicates that haskell-platform is required. I'm using dev-lang/ghc-6.12.1, which I think is a couple of versions ahead of haskell-platform. Dependency conflicts prevent me from installing haskell-platform, which probably means I can't install Yi until a version of dev-haskell/haskell-platform >= 6.12 is available. Reproducible: Always Steps to Reproduce: 1.emerge haskell-src-exts Actual Results: Emerge fails due to missing dependencies. Expected Results: Emerge should either install the dependencies along with haskell-src-exts, or notify the user of a conflict.

Syb stuff was removed from base-4, but left in base-3. Thank you, Amy! If you really like to try YI, you could try to use in-overlay ebuilds: http://www.haskell.org/haskellwiki/Gentoo#Gentoo_Haskell_Overlay layman's overlay name is 'haskell'
