Is it possible to dynamize "requires" at RPM build time?

Unfortunately, I don't think there's any way to do this in a reliable
and generic fashion except in the cases where we're helped by the
upstream library maintainers[1].

If you were to automatically do some sort of dep on, eg, 'pkg-config
--modversion gtk+-2.0', then you could end up with a newer requirement
than you really need[2]

[1] eg, by using symbol versioning at which point
findProvides/findRequires actually will do a requirement on the
versioned form of the library; see glibc deps
[2] Right now, it would say I need gtk+ 2.10.2 for anything built
against gtk2.  Realistically, many of them would work for pre gtk+ 2.10
(as long as they're not using new gtk+ features) but they'd definitely
work with say gtk+ 2.10.1
