In case anybody is interested, I found an answer at the following
location:
http://osdir.com/ml/python.pyinstaller/2006-02/msg00069.html
Apparently there was a patch submitted Februrary 2006.
Using the fix suggested by the author, I was able to use
win32com.client.gencache.EnsureDispatch(), as well as
win32com.client.CastTo(), without any trouble.
