Yes, OS X comes with MPI. That's the one that points to gcc4.2 on Snow
Leopard and gcc4.0 on Leopard.

The point is that (retarded as they are), you have Apple-blessed
versions of Python, OpenMPI, GCC, X etc. as part of the OS. When one
insists on doing everything from MacPorts, you bypass this existing set
of tools entirely.
