I currently have 6.10.1, 6.10.3 and 6.12.1 installed (openSuSe 11.1), no problem. On my previous computer (SuSE 8.2), I had every release from 6.2.2 to 6.8.2, no problem either. > we do this with Gentoo because despite there > being some distribution-specific architecture in place to be able to > switch between compilers (used for GCC, Ruby, Python, etc.) we haven't > resolved how to deal with dependency problems when a library was built > with one version of GHC and then you try to build something that depends > upon it with another version of GHC (since the package manager _knows_ > that the dependency is installed, yet GHC is vehement that it knows > nothing about it). Ah, but one shouldn't use a package manager for Haskell packages. Cabal is far superior to all of them 8-) _______________________________________________ Haskell-Cafe mailing list [email protected] http://www.haskell.org/mailman/listinfo/haskell-cafe
