Ah, you have the buggy Apple preprocessor, so you get

                Unable to parse OpenMPI version from header. Probably a
buggy preprocessor
                  Defined "HAVE_OMPI_MAJOR_VERSION" to "unknown"
                  Defined "HAVE_OMPI_MINOR_VERSION" to "unknown"
                  Defined "HAVE_OMPI_RELEASE_VERSION" to "unknown"

In the new release, we catch this. However, I think then the make check
fails.

Satish, how is the make check for this version number done?

  Thanks,

What most experimenters take for granted before they begin their
experiments is infinitely more interesting than any results to which their
experiments lead.
