There has been some instability in rawhide pkg-config in the last few days. The reason is that I've built the long-overdue 0.24, which turned out to have a few small issues.
One remaining problem that is still causing some build problems is https://bugzilla.redhat.com/show_bug.cgi?id=596433 where we need to update find-requires.pkgconfig to match the behavior change that our --print-requires patch underwent on its way upstream.
Sorry for the inconvenience,
Matthias
