I don't see why we'd add this as a new package, rather than simply
adjust the capabilities/inputs of the "petsc-openmpi" package.

I believe PETSc's configure script will handle much of the flags on its
own if it's provided with "--with-metis", "--with-scotch",
"--with-mumps", "--with-scalapack" flags.

I have not tried building this yet, but I will give it a try later.
