Afraid compilers don't help when the param is a void*... It looks like this is consistent, but I've never tried it under that particular environment. Did prior versions of OMPI work, or are you trying this for the first time?
One thing you might check is that you have the correct PATH and LD_LIBRARY_PATH set to point to this version of OMPI and the corresponding PBS Pro libs you used to build it. Most Linux distros come with OMPI installed, and that can cause surprises. We run under Torque at major installations every day, so it -should- work...unless PBS Pro has done something unusual.
