Fortran 90 and BeoMPI

[Frank Muldoon]

I just got done trying linking directly to the mpi libraries using 2 F95 compilers (Lahey & NAG).  Both behave the
same way as before (output below).  I was under the impression that it was often necessary to have separate builds
for f90/f95 and f77.  For instance the MPICH install guide says "During configuration, a number of F90-specific
arguments can be specified. See the output of configure -help. In particular, when using the NAG Fortran 90
compiler, you whould specify -f90nag."

Thanks,
Frank
