Yes...

So far, I've added

  --with-parmetis=1 --with-parmetis-dir=/usr/include/parmetis --download-mumps=1

But PETSc is complaining about ScaLAPACK. Is it possible to use the
Debian package? I'm using OpenMPI (from Debian) but
libscalapack-mpi-dev seems to require mpich.

Which is the simplest way to get MUMPS running?
