--- Comment #3 from Jens Petersen petersen@redhat.com --- It is better to patch the flag default in the .cabal file actually for tools like cabal-rpm - sorry didn't think to mention that earlier. Since the flag is only needed for ghc > 7.2, ie currently only f18 and f19, it is not needed for epel currently.
