I'm able to package as user buildmeister. It still fails with debuginfo, so 
I'll try to dig into that, and look into adding the pre/post stuff.

I also tried using "rpmbuild -tb" (build from tarball) and that fails 
because it wants the spec file in the root of the tarball. Kind of 
pretentious of the original RPM devs to require that, of course. ;)
