Yes, I have seen this too.  I don't know why this seems to be a
problem, but it is.  I know /lib64 and /usr/lib64 are normally
accounted for, but why /usr/X11R6/lib64 is not, I don't know.  Is this
a standard directory?  Or is it specific to Fedora?  Was it added
later than the other 64-bit lib directories to the standard?
I think the x-libraries definition is the right fix (or at least it
works right).  Should probably be combined with a "%ifarch x86_64"
block if you want to do it right.  If you are just rebuilding the rpm
for yourself, just add the line if necessary.
Well, I decided to go to Google for a little bit and (to answer my own
questions) found this:

Looks like it *is* the standard to have the X11 lib64 directory. 
Perhaps devleopers simply overlook it.  Maybe someone more
knowledgeable with rpm and rpmbuild can say if this is something that
rpmbuild or if it should be handled in the spec file.
