[petsc-users] Issue about using MUMPS with PETSc

[Satish Balay]

And petsc-3.1 presumably was using 'metis' - and not 'scotch' - so you
could try rebuilding mumps with metis/parmetis.

right now we do:

    if self.parmetis.found:
      orderingsc += ' -Dmetis -Dparmetis'

Should this splitup to a separate dependency on metis?
