Redirecting to the list.  Any chance we could have replies automatically 
sent to the list?

Be sure these are the right mpicc and mpicxx versions and not another 
MPI's.  I suspect the .la line is roughly equivalent to what I sent.

Hmmm, looks like it doesn't think that your paraview is really an MPI 
program.  OpenMPI's orterun/mpirun/mpiexec (all the same) can launch 
non-MPI programs on multiple nodes as well.

However, I've never actually compiled paraview with openmpi (yet), so I 
don't have any real experience.  I'll have to try it sometime though.
