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
