Building RPMs: legacy syntax unsuported

[uth]

So far, every RPM I tried to build myself has failed with a "legacy syntax unsupported" error. The sample below from heretic. Is there an easy workaround or will every old specfile need to be rewritten?

# rpmbuild --rebuild heretic-1.1-1.src.rpm

install the src rpm
