I've now picked this back up. It's available in
http://cgit.freedesktop.org/~mattst88/glu/

I've addressed Jakob's comment about putting the src/ folder back in,
and I've confirmed that it passes distcheck.

I'll bump the package version to 9.0 (to correspond to Mesa-9.0 -- the
first version of Mesa that won't have bundled GLU) but the soname is
still 1.3.x to match previous versions. OSMesa linkage should work,
but I haven't touched the name mangling stuff. Tom (CC'd), if you care
about this...

I'll send a patch to strip GLU out of Mesa once we get this into its
own /mesa/glu/ repository.

Please review and then move to /mesa/glu/.

Thanks,
Matt
