Apple has removed MPI from recent OS X versions so it is not available there.

So currently, you have to install whatever MPI implementation you prefer from sources since neither the libraries nor the toolchain are available. What Apple used to ship was OpenMPI which still exists, but to my best knowledge there is no official, maintained binary for OS X so on Mavericks we have nothing to build CRAN binaries against, so you have to install everything from sources.
