You should be able to find the version of spambayes that setup_all.py
is trying to use. Does it in fact have a directory called resources?

At the top-level spambayes directory, there is a spambayes/windows/setup_all.py. That suggests to me that something about the way the Windows package is built equates the spambayes/windows directory with spambayes.
That's about all I know. I have never done anything with Windows development.
