Compiling MPI with f90 support on Snow Leopard

Good day friends,

I am trying to compile the latest stable iteration of MPI, downloadable from, on my MacBook Pro that utilizes the Snow Leopard OS, 10.6.4. I have installed both gfortran and gcc, both obtained from

When I compile the MPI program, it does not do so with f90 support. I need it to has this feature for another program, DL_POLY 2.17, a molecular dynamics simulation program available for academic institutions. The makefile to compile the parallel executable calls for mpif90.

MPI with f90 Fix

OpenMPI installs without a hitch with f90 support on 10.6.4. I use the following with the Intel compilers (free Beta test of version 12 until December).
