My point was that I'm not aware of any packaging systems that don't have a global "installed"/"not installed" bit for each package, which isn't suited to handling Haskell libraries.
I don't agree - you are assuming there is a one to one correspondence between Cabal libraries and binary packages. The normal way to resolve this is that each source library gets compiled to multiple binary packages, which optionally can be unified as virtual packages 'providing' specific functionality. E.g. on my system (Ubuntu), I installed the virtual package 'ghc' to get GHC 6.6(.1?) which is actually provided by the package called 'ghc6'. In addition, I have the QuickCheck library installed, from a package named 'libghc6-quickcheck-dev', making room for libhugs-quickcheck-dev' etc. -k
