Fortran 90 and BeoMPI

I would suggest ditching the mpif90 wrapper altogether and just invoke the
Fortran compiler directly.

'lf95 -lmpif myfile.f90' (or equivalent command line)

The point of the compiler wrappers that some MPI vendors ship is usually
one of:

	1. hide the rat's nest of little libraries from the end user

	2. maintain compatibility with an earlier MPI that (see 1)

These reasons leave a bad taste in my mouth. You should be able to treat
MPI like any other library.

Let me know if this works for you.
