patch applied (cabal-install): Hide any available base and ghc-prim packages from the dep resolver

Wed May 21 08:37:00 PDT 2008 Duncan Coutts <duncan@haskell.org> * Hide any available base and ghc-prim packages from the dep resolver Previously if the base package was available on hackage then the dep resolver might try to upgrade it. Unfortunately that's almost certainly technically impossible at the moment. So now since the dep resolver does not see these available packages it cannot pick them. This should fix ticket #174.
