YES! I have not gotten Ippolito's reference to setuptools working yet 
on my system but I do have a setup.py that runs SWIG. Distutils has 
limited support for SWIG in it. The problem is that SWIG gets run 
(and creates the shadow .py file) after distutils has already handled 
.py files. So you have to either do "python setup.py" twice or 
explicitly do "python setup.py build_ext install" so that the 
build_ext command runs SWIG and builds the extension module and then 
install goes back and copies everything where it needs to go.

Here is a simple setup.py for this (somewhat modified from mine to 
make it generic but it should work). If you need to add source files 
beyond what SWIG produces I think you add them to the list that has 
"package + '.i'" in it.

#!/usr/bin/env python

from distutils.core import setup, Extension

# package is the the module name and the name of the SWIG .i file
# Probably good to use the same in py_modules at the bottom.
package = 'mymodule'
version = '0.1'
# add any directories to search for include files
include_dirs = ['../src',]
# add any directories to search for libraries
lib_dirs = ['.',]
# add any libraries name to link against
libraries = ['readline','termcap','X11']
#extra_comp_args = []
extra_comp_args = ['-Wno-strict-prototypes',]

setup(name = package,
       version = version,
       description = '',
       author = 'My Name',
       author_email = 'myname at somewhere.com',
       url = 'http://',

       ext_modules = [Extension('_'+package,
       py_modules = ['mymodule',]
