Unfortunately, there is no such thing as a per-library rpath -- either you
have an rpath, or you don't, and it applies to all libraries directly loaded
by the binary (shlib or application) being built with the -R option.

The rpath, while global in the built binary, *is* ordered, which is why
removing the -R for /home/reed/pkg/lib worked; the ELF runtime linker is now
searching in /home/reed/xorg/lib first, as it's the only one left in the
rpath.  However, that is not an argument in support of removing the -Rs
from pkgsrc's .pc files.

I think what you really want here is the ability to detect "builtin"s in
more than just the default /usr location.  That way you can build xorg
directly, then rebuild pkgsrc packages to use that rather than one in the
pkg tree.
