I found the solution. For reasons I have not yet determined, I had
version of cpp from 2005 in my ~/bin directory which was before /usr/bin
in my path. I have no idea where it came from or why it was there but
once I removed it Open MPI compiled and tested fine. Many thanks to both
Jeff and Paul for their suggestions which led me to the solution.
