It's not a good idea to build rpms as root (unless in a throw-away vm). Build 
as user or even better using mock.

That said, many a broken rpmbuild can be blamed on missing the
redhat-rpm-config package (containing lots of rpm macros).

If that's not the case I'd try rebuilding a known good src.rpm with 
"rpmbuild --rebuild foo.src.rpm" to validate your setup.
