I think Satish now prefers

  --with-cc=${MPICH_HOME}/mpicc --with-cxx=${MPICH_HOME}/mpicxx --with-fc=${MPICH_HOME}/mpif90

That still requires with-mpi:

         UNABLE to CONFIGURE with GIVEN OPTIONS    (see configure.log for details):
Did not find package MPI needed by PTScotch.
Enable the package using --with-mpi

Makes sense, actually, but I ran into it.
