Could you be more specific here? Is it a compiler or scipy issue? And
which parts are failing if the latter?

256 is the return status of the command. If this means success in HP then
you can add some hooks to fortran_compiler_base.get_version method, or
better yet, rewrite it for the hpux_fortran_compiler so that with this
status value it will return the version of the compiler.

BTW, you can try also --fcompiler=HP option to force to look only for this
compiler, eg.

 setup.py build build_flib --fcompiler=HP

Note that build must precede build_flib.
