That's only one half of the issue.

In case of the perl(Gtk2::*), rpm now collects "use base ..." requires, 
but misses to collect and provide the XS-symbols they are implicitly 
provided through.

I.e. in a perfect world, rpm's deptracking needs to be extended to 
collect XS-symbols,

A quick hack applicable to the perl-Gtk2-* packages would be to run
some "nm -sD --undefined ..." based script to generate a list of these 
Provides:

Rough uncooked example:

nm -sD --defined /usr/lib64/perl5/auto/Gtk2/Gtk2.so \
| grep -E 'XS_Gtk2.*_new$' \
| sed -e 's,^.*XS_Gtk2,perl(Gtk2,;s,__,::,g;s,_new,),'
