This change allows use of the with-packages wrapper in user profiles that are being updated with "nix-env -u \*". The previous name this expression generated was considered by Nix to be an older version of "ghc-7.0.4-wrapper", because that name has a higher priority. svn path=/nixpkgs/trunk/; revision=33325
