> You can't build for MPI without having some MPI library (with tools) installed. A simple way to install OpenMPI on OSX is to use Homebrew ( After Homebrew itself is installed, install MPI using "brew install openmpi". I think that is all you need.

BTW if you are just looking into using all cores on your local machine, you'd better use the -fork option of bleeding-jumbo - MPI is not needed at all!
