Broken by <359b069f7e4700bee337588eab0a9d83cac94010>. I'm not suggesting you fix this right now, but our current RPM build process is very broken by design, because we are completely ignoring dependancies between packages. We've hacked around this by culling the BuildRequires lines from the spec file before running rpmbuild, and relying on a bit of luck to have the rpmbuild find the stuff we just built into $VIRT_PREFIX. As this test suite problem shows though, this is very fragile.

One way to fix this is to create a yum repo populated with all RPMs we build during CI. Then setup a mock vroot to do the builds in, which includes this local yum repo. That way we can honour the RPM deps correctly getting a more accurate test of RPM build process. My main concern with this is that mock is kind of slow to bootstrap the initial vroot, so this would slow our CI somewhat.
