Heh.  I actually sent that last note, then started going down the macro road
myself...  Initially I looked at just doing something specific to this, but
broke it out and wrote something a touch more granular:

http://fedorapeople.org/~cweyl/macros.perl

With that in place, it's possible to stick a "%{?perl_default_filter}", say
before %description, causing all private .so's to not be scanned by the
requires scripts...  It also prevents anything under %{_docdir} from being
scanned for either prov or req.  We can also filter things both at the file
level (preventing them from being scanned) or at the generated req/dep
level.

If the macros look sane, I'll open a RFE bug against the perl package to ask
that it be bundled and delivered as /etc/rpm/macros.perl.

While this is aimed at solving our issues, it should make dealing with wonky
auto req/provs much easier. :)
