patch applied (cabal-install): Use installed constraints instead of hiding versions of the base package

Fri Dec 19 11:37:40 PST 2008 Duncan Coutts * Use installed constraints instead of hiding versions of the base package We want to stop cabal-install from accidentally trying to upgrade the base package since this doesn't work in most cases. We used to achieve that by deleting the base package from the available package index. We now do it by leaving the package index as is and instead adding a constraint that we pick only an installed version of base. This is a nicer hack and has the potential to give better error messages.
