Details:

When building against openmpi-1.5 or later, the following error occurs.  I've
seen this on OS X using Fink, but the error is a missing member, and seems
like it should occur elsewhere, too:

/sw/bin/mkoctfile-3.6.4
-I/sw/include/openmpi/opal/mca/hwloc/hwloc132/hwloc/include -I/sw/include
-I/sw/include/openmpi -L/sw/lib/openmpi -lmpi_cxx -lmpi -lm MPI_Iprobe.cc
MPI_Iprobe.cc:38:14: error: no member named '_count' in
'ompi_status_public_t';
      did you mean '_ucount'?
  tmp = stat._count;
             ^~~~~~
             _ucount
/sw/include/mpi.h:346:12: note: '_ucount' declared here
    size_t _ucount;
           ^
1 error generated.

I used the following patch to address this:
