Something like the following should work...

from numpy.distutils.core import setup, Extension

my_ext = Extension(name = 'my_pack._fortran',
                              sources = ['my_pack/code.f90'])

if __name__ == "__main__":
    setup(name = 'my_pack',
             description = ...,
             author =...,
             author_email = ...,
             version = ...,
             packages = ['my_pack'],
             ext_modules = [my_ext],
          )
