Out of curiosity, have you tried using cabal-dev? It's far from a panacea, but it does mitigate library version issues. And, AFAIK, it's getting rolled into cabal proper Real Soon Now (see: http://hackage.haskell.org/trac/hackage/wiki/SandboxedBuilds... ).
Yes, and I wish I could remember why it didn't work, but this was several months ago.
If that's becoming standardized, the way pip/virtualenv are becoming a standard part of Python 3, that's good news. Maybe this problem is already on its way to being solved - let's hope so!
