I used the info provided on the openmpi users list and used the command
./configure --prefix=/usr/local --enable-mpi-f77 --enable-mpi-f90
F77=gfortran FC=gfortran FFLAGS="-m32 -std=legacy" --with-wrapper-
fflags="-m32 -std=legacy" --with-mpi-f90-size=medium --enable-mpirun-
prefix-by-default FCFLAGS="-m32" --with-wrapper-fcflags="-m32"
and got
/usr/local/bin/ompi_info
....
Fortran77 bindings: yes (single underscore)
Fortran90 bindings: yes
Fortran90 bindings size: medium
C compiler: gcc
C compiler absolute: /usr/bin/gcc
C++ compiler: g++
C++ compiler absolute: /usr/bin/g++
Fortran77 compiler: gfortran
Fortran77 compiler abs: /usr/local/bin/gfortran
Fortran90 compiler: gfortran
Fortran90 compiler abs: /usr/local/bin/gfortran
C profiling: yes
C++ profiling: yes
Fortran77 profiling: yes
Fortran90 profiling: yes
C++ exceptions: no
Thread support: posix (mpi: no, progress: no)

So this looks good.
Thanks for the postings.
Now I plan to try to get it working with Absoft and maybe with POOCH
