OK, good. I think it is okay that Dorsal builds SCOTCH without
-DSCOTCH_PTHREAD since this requires the MPI library to support the
MPI_THREAD_MULTIPLE level. The OpenMPI library in Debian/Ubuntu and in
Mac OS X 10.6 does not support this.

One can run "ompi_info | grep Thread" to check if the
MPI_THREAD_MULTIPLE level is supported by the OpenMPI library. It is
not supported if the output is "mpi: no" and SCOTCH should be built
without -DSCOTCH_PTHREAD.
