I have oodles of installations of OMPI on my machines; they don't
interfere with each other.

So let's see if we can figure out why yours don't seem to play well

- Check that /opt/mpi_sun and /opt/mpi_gfortran* are actually distinct
subdirectories; there's no hidden sym/hard links in there somewhere
(where directories and/or individual files might accidentally be
pointing to the other tree)

- does "env | grep mpi_" show anything interesting / revealing? What
is your LD_LIBRARY_PATH set to?

- what does ldd on the various .so files in /opt/mpi_sun/lib/ show?
Are they linked against files in their own tree, or the other tree?

- run "mpif90 --showme" through strace; does it show anything
