Description of problem: Epoch:0 was removed from ghex spec file. ghex was rebuilt. ghex-devel requires %{epoch} in the spec file - but since epoch wasn't there it requires LITERALLY %{epoch}, which always fails on lookup. Needs to be fixed with 0 in place of %{epoch}
Fixed in CVS. I'm to blame. In packages I had testbuilt and prepared in CVS, I didn't want to touch epochs because I wanted to leave that decision to the packager owners. ghex is one package where I picked up Matthias' euphoria for deleting epochs, and promptly ran into the trap. Seth, could you ran a "rpm -qpR * | grep epoch" or something like that in full pre-extras tree? Hopefully there are no other cases found.
Michael, I ran it last night after I saw ghex-devel. There are no others. Thanks. I'll build this and close.
