Thanks for responding (and thanks for starting py2exe!). Yes, my build 
script always wipes out the build and dist directories first.

The problem turned out to be (it was right there in the traceback, but I 
glossed over it at first) that numpy includes their own ctypeslib, and 
*that* version was 1.0.2. Now, I'm still not sure why it mattered in the 
exe but not running just the script, but upgrading numpy resolved the issue.
