Hmm; that's odd.  OMPI should pick up the PSM libraries by default if  
they're in the linker's default path.

Note that there is an outstanding issue with the Pathscale C++  
compiler and the Open MPI C++ bindings:

     https://svn.open-mpi.org/trac/ompi/ticket/1326

It *looks* like a Pathscale bug (some C++ constructors are definitely  
not firing), but I don't know for sure.  The ball is in Pathscale's  
court -- I initially reported it about 2 months ago; our last e-mail  
exchange about it was within the last week or two.
