Looking at your config.log, it looks like OMPI correctly determined that the Fortran INTEGER size is 8. I see statements like this:
#define OMPI_SIZEOF_FORTRAN_INTEGER 8
Are you sure that you're running the ompi_info that you just installed? Can you double check to see that there's not another ompi_info somewhere in your path that you're accidentally executing?
