These are the same SRPMS as always; there is no difference to > how they are generated with respect to previous releases, only in > how the ISOs were generated. either the issue wasn't present until now (no arch hardconding in BuildRequires before FC5), or nobody noticed.

The cleanest way would be for rpm to no hardcode these values but to always evaluate them. E.g. have rpm -qRp ignore the require tags in the header and reparse the specfile. But that's too invasive of a change to fix something only nitpickers and buildsystems notice ... :/ I guess the only workaround is unpack-repack: rpm -i --nodeps funny-1-2.src.rpm rpmbuild -bs --target myarch funny.spec </ugly> The resulting src.rpm will be arch-specific for the target platform containing the "real" BuildRequires. -- Axel.Thimm at ATrpms.net
