Sorry for the late chime-in; just now catching up on petsc-dev. MUMPS
doesn't claim to use anything considered recent in terms of METIS. As
for as I can see, they still haven't applied my patch to update MUMPS to
work with METIS 5.0:

The same goes (as of this afternoon) about George not updating METIS
with the patches we sent a while back.
