You don't need setuptools at all. Just write a setup.py file using the  
standard distutils module, and execute:

python setup.py bdist_wininst

It will create an executable installer. A simple setup.py script looks  
like this:

---begin setup.py---
 from distutils.core import setup

setup(name='My Package',
       version='1.0',
       description='This is the description of myPackage',
       packages=['myPackage'],
      )
---end setup.py---

Read the "Distributing Python Modules" document in your Python  
installation, or at <http://docs.python.org/dist/dist.html>

Well... don't use an egg in the first place :)

There are many other problems with egg files... (did I menction that I  
hate eggs?)
