* Move the composition of Haskell packages out of all-packages.nix into haskell-packages.nix, which depends on an instance of GHC. This allows a consistent set of packages to be built with the same GHC. For instance, $ nix-build -A haskellPackages_ghc683.xmonad builds xmonad and all its dependencies with GHC 6.8.3, while $ nix-build -A haskellPackages_ghc6102.xmonad does the same with GHC 6.10.2. This is the same technique used with kernelPackages. It also means that we don't need things like "cabal682" and "cabal683" anymore. * The setup hook is now in a separate wrapper package so that we don't have to recompile all of GHC every time we want to make a small change. * cinelerra: this package appears to have an accidental dependency on the "X11" Haskell package. svn path=/nixpkgs/trunk/; revision=15125 2009-04-18 14:47:11 +02:00			`{stdenv, ghc}:`
