What version of Python and Twisted are you running?

I think you are right that pbs needs to use mpirun/mpiexec to start
multiple engines using a single PBS job. I am not that familiar with
SGE, can you start mulitple processes without mpi and with just a
single SGE job? If so, let's try to get that working.
