Trying to install openmpi, read that:
Could not determine if REAL*16 bit-matches C type
Ran brew doctor, and it's giving me:
Your system is raring to brew

There were some issues with recent gfortran builds in Homebrew. Try reinstalling it with brew rm gfortran; brew install --fresh gfortran. If the error persists, head over to the Homebrew GitHub page and report it as a bug: https://github.com/mxcl/homebrew/wiki/Troubleshooting.

There seems to be an issue with the gmp and mpfr bottles, which are dependencies of gfortran and thus open-mpi. Try doing brew rm gmp mpfr; brew install --build-from-source gmp mpfr open-mpi
