Change in ghc-6.2.2 distribution files

Hi, Did the file ghc-6.2.2.tar.bz2 get changed without the version number being changed? The md5 sum of the files has changed, breaking the darwinports and presumably the *BSD ports builds as well. I didn't see any notice to the list, so I'm not sure if the change is intentional, or if the wrong file is being distributed. Best Wishes, Greg
