Well, I did not have an *older* version of MPI installed. I just had
the LAM-MPI version v7.0.4 installed using the MacOSX disk image. After
installing the image, I wanted to compile some fortran code, so I
downloaded the source code and installed LAM enabling the fortran
bindings.

Here is the output:
/opt/ibmcmp/vacpp/6.0/bin/xlc++ -I/usr/local/include -D_REENTRANT
-L/usr/local/lib -llammpio -llammpi++ -llamf77mpi -lmpi -llam
