patch applied (cabal-install): Fix selecting paired packages

Mon Oct 6 23:29:30 PDT 2008 Duncan Coutts * Fix selecting paired packages Previously when we selected base 4 (and as a consequence slected base 3 too) we didn't properly trace the dependencies of base 3 so if nothing actually required base 3 then we ended up with base 3 in the solution but not with syb which it depends on. Consequently the solution was invalid. Now we select the paired package properly (hopefully).
