This is not an issue with Open MPI; it's an issue with how the Fortran compiler works on

compiler convention.
Or you can use the new Fortran'08 C interop stuff (BIND(C)), in which you can
specify the C symbol name in the Fortran code. Be aware that while this is
supported in some Fortran compilers, it is not yet necessarily supported in the
version of gfortran that you may be using.
iso_c_binding was introduced in Fortran 03, and supported in gfortran at
least since version 4.4, which is about as old a version as you have any
business trying (no older ones have adequate documentation remaining on
line).
Also, FWIW, OMPI 1.6.1 is ancient. Can you upgrade to the latest 1.6.x version
of Open MPI: 1.6.5?
