[Haskell-cafe] capri cabal-dev virtualenv cab

[Rustom Mody]

Does anyone give me a little comparison of these?

What would all my requirements be? Not sure... these seem important for me

1. Need to sandbox not just haskell-projects but ghc (different
compilations/versions) itself
2. Stability of the (sandboxing) tool
3. Correcting the deficiencies of cabal (eg inability to uninstall,
quarrels between cabal and apt etc)

OS: Debian/testing
System haskell: 7.0.4
