Well, not sure what I can advise. Check to ensure that your LD_LIBRARY_PATH is pointing to the same installation where your mpirun is located. For whatever reason, the processes think they are singletons - i.e., that they were not actually started by mpirun.
You might also want to ask the mpi4py folks - we aren't very familiar with that package over here. It could be that you need to configure it for OpenMPI as opposed to mpich.
