[Distutils] How do I modify the swig options in my setup.py

 From inside setup.py, use swig_opts. See the following example:

import sys
from distutils.core import setup,Extension

setup (name = "sai",
        version = "2.0",
        description = "SAI Python wrapper",
        author = "Lars Immisch",
        author_email = "lars at ibp.de",
        ext_modules = [Extension("_sai", ["sai.i",
                                          "errorobject.c",
                                          "symname.c"],
                                 swig_opts = [ "-modern", "-new_repr",
                                               "-I..", "-I../../include"],
                                 include_dirs=["..", "../../include"],
                                 library_dirs=["."],
                                 libraries=["nsl", "pthread",
                                            "cSARU-genappl-api", "saru"])],
        py_modules = ['sai']
        )

Wrong typemaps ;-)

This sort of question is best asked with a minimal example on the swig 
mailing list, but do have a look into typemaps in the documentation.

A lot of useful typemaps are in python/typemaps.i.
