Compiling OpenMPI on MacOSX

First, you will need a proper gfortran installed on your system. This version (gfortran 4.2.3)worked for me. After installing that download and extract OpenMPI. Here's the config line that I used
./configure --prefix=/Users/USERNAME/pkg/openmpi-1.4.2-install\
F77=gfortran CFLAGS=-m64 CXXFLAGS=-m64 FFLAGS=-m64
then
make
make install
Voila!

If you wish to install to the default location (/usr/local/ etc...) remove the prefix option.

    FWIW: be careful of replacing the OS X-default installed Open MPI. We typically advocate installing in a non-default location (such as /usr/local or whatever). As long as you use the "mpicc" and friends installed with your new Open MPI install, it should link to the right shared libraries.
