Well... I used the tool and found missing dependencies and just copied
them into site-packages.
There were two.  Then when I put those two in there and ran
dependencywalker again, I had 6 more missing.
I found all of these dependencies in a "bin" directory of the program
which I'm trying to create bindings for.
The one I couldn't find was MSVCR80.DLL but my python module imported
fine so maybe its not a big deal (actually, if I throw one of their
dll files into dependency walker it shows the same thing).
This was just with me wrapping one (very basic) routine.  I would
imagine as I wrap more and more, I'd need more and more dll files.

I think rather than copying .dll files around, I'll just put my .pyd
file in their 'bin' directory and set PYTHONPATH environment variable.

Things are starting to look promising.

I now have to deal with other issues (coming up in a new python-list thread).

Thanks a bunch Ulri.
