py2exe

I've been using py2exe for a while, but I keep running into some problem
importing some modules.

I have a program that uses the "pywinusb" library.  The pywinusb library is
in the same folder as the program file that's being compiled.

main.py

    import pywinusb
    ...

And pywinusb uses ctypes:

    import ctypes

The program runs fine if I just run it in python.  But when I use py2exe, it
gives the error:

    Traceback (most recent call last):
      File "my_file.py", line 34, in <module>

        raise ImportError, "No module named " + qname
    ImportError: No module named ctypes

The line numbers may be off, as I've added a few debug statements.  I can
determine that the error happens because "ctypes" is in mf.py ModuleFinder's
badmodules list.  From what I can tell, the order is this:

-py2exe finds the pywinusb.hid module, and finds all the import statements.
-It sees "import ctypes", and calls ModuleFinder.find_head_package() with
parent==pywinusb.hid and name=="ctypes".
-find_head_package() then calls import_module() with partname == "ctypes",
fqname=="pywinusb.hid.ctypes", and parent==pywinusb.hid.
-import_module() then calls find_module(), which then calls
imp.find_module() with name=="cypes" and
path=="C:\path\to\project\pywinusb\hid", which fails since ctypes is not in
pywinusb's folder.

At this point, since imp.find_module() has failed, the "ctypes" module is
added to the badmodules list and therefore fails the entire py2exe build
process.

It seems that if a given module is not found in the folder of the
parent/importing module, then py2exe should attempt to find it using
imp.find_module(name="ctype", path=None) as a secondary.  Otherwise, seems
like there's no way to properly find any modules imported from any child
module.

I've tried adding include=["ctypes"] in the setup file, but that doesn't
work - ctypes gets put in the badmodules list, and therefore fails no matter
what.

Is there something I've overlooked?  Is this just a bug with how ctypes
attempts to find modules?

Thanks!
