 After upgrading python31 on one of my systems, my software began to 
 fail:
 
 Traceback (most recent call last):

 During handling of the above exception, another exception occurred:

 Installing py31-expat-0nb5 fixed the problem but is that correct? The 
 python31 package provided lib/python3.1/xml/etree/ElementTree.py which 
 used its provided lib/python3.1/xml/parsers/expat.py which required 
 outside package py31-expat-0nb5 which provides only 
 lib/python3.1/lib-dynload/pyexpat.so (not other files).
 
 Is it okay for the provided python3.1 modules to require an outside 
 module?
 
 Then again maybe that is okay since that is the way I have been using 
 python31's sqlite3 for over a year.
