I'm not quite sure how it evolved that we make tarballs in tightly controlled conditions, but the SRPM is just made by hand on my cluster (which is subject to upgrades, etc.). Hrm. :-\
Building on RHEL 4 shouldn't have any impact. If anything, it would make
things worse instead of better, but I think that's unlikely. This
problem has to do with changes in RPM itself from RHEL5 to RHEL 6.
Ideally, you should be using Mock to build your RPMs, and build a
separate set of RPMs for RHEL 3,4,5,6,... It's a PITA, I know, but it's
really the best way to build RPMs without any dependency gotchas.
