You should be able to verify which compilers were used for your openmpi, e.g.
mpif77 -v
As mpif77 would be just a wrapper, the actual compiler (g95, or a gfortran
of the last 2 years, or a commercial Fortran?) should also be present on
that system. In order to make a lam mpif77 with the same Fortran
extensions, you would need to configure and build lam with the same
Fortran compiler.
