I don't know if it's the "proper procedure", but I have compiled stuff
from Fedora 11 and Fedora 12 on this Centos 5.4 machine.  (geany,
fbreader, vice, buoh, etc.)  I found that I can't directly rebuild the
srpm due to the different checksumming method that new Fedora uses, but
it's easy to rip the F11/12 srpm apart by right-clicking on it with
Natuilus and saying "extract".  (I'm sure there is a commandline-method
to do that too but this works and I never looked into it any further
than that.)

Move the .spec file into ~/rpmbuild/SPECS and put the source into
~/rpmbuild/SOURCES.  Edit the spec file if it needs any fixing, then
"rpmbuild -ba myfile.spec".  You now have a native Centos 5 rpm and
srpm.

This wouldn't work with stuff that actually does have newer dependencies
than Centos provides without being more work than it's probably worth,
of course.  Sylpheed is one example of this situation.  Since the older
version of Sylpheed that I did find for Centos (2.0.4) doesn't have bold
text for unread message titles in the message listing window, I was
rather disappointed.  My solution was to move my email into Evolution
instead.

The nice thing about recompiling F11/12 stuff on Centos is that Fedora
distributes the latest versions of stuff and almost all of the packaging
work is already done for you -- all you need to do is tear the Fedora
srpm apart and rebuild it for Centos.
