I don't know anything about the NDP Fortran compiler, so I don't know if
you can make it use 64 bit mode.

The above line indicates that you didn't do a "make distclean" or remove
the file "config.cache" before executing the configure script.  Thus,
some of the following results result from a previous execution of the
configure script.
