I'm not on Lion right now so I'll check later, but I don't think I'll be re-packaging it for that ;). > But I admit that it's all still a bit confusing.

Obviously, it's something that the authors didn't anticipate so there is no provision for labeling that mix ;) - the build simply shows the branch version which is gcc-4.2.1 5666.3. Given that Apple has no Fortran in their branch, there is really no "corresponding" Fortran. Cheers, Simon >> You can use either (as the post said).
