This *may* be the problem here.

It's been a loooong time since I've run under PBS, so I don't remember if your script's environment is copied out to the remote nodes where your application actually runs.

Can you verify that PATH and LD_LIBRARY_PATH are the same on all nodes in your PBS allocation after you module load?

FWIW, since you've installed OMPI 1.6, you may want to uninstall the Open MPI that may have been installed by your OS.
