A few of the bugs on
https://bugzilla.redhat.com/bugzilla/showdependencytree.cgi?id=multilib
are assigned to to RPM. The most important one is probably the lack of
arch-specific Requires: and BuildRequires: (#235755).
I don't think we'll manage #235757 in time for Fedora 8 but it would be
good to get it done (and the packages updated accordingly) for Fedora 9.
(Note that comments 3-19 are about the short-term hack we did for F7,
not the real subject of the bug).
Thoughts on #235758 would be appreciated.
