Hi Jim:
Well, from my experience, you don't link OpenMPI/MPICH2/etc. with the
R binary per se. You build R the usual way. And, then you do an
R CMD INSTALL Rmpi.tgz
At that stage, you will need to be concerned with whether the
appropriate headers and libraries exist. This step will give somewhat
informative feedback about that.
