cabal

Hi, currently I've got a problem installing from hackage. using: GHC (package manager) version 6.10.0.20081019 cabal-install version 0.6.0 using version 1.6.0.1 of the Cabal library I get: Building network-2.2.0.0... Network/URI.hs:128:7: Could not find module `Data.Generics': it is a member of package base-3.0.3.0, which is hidden even with: cabal install network --constrain="base<4" (A similar problem happened with Shellac.) How is the smart selection between base-3 and base-4 going to work? Eventually, I want to install hxt-filter and Shellac-compatline. (The interface in editline changed for Shellac-editline.) Cheers Christian
