Well, for a stable production, I believe you'll want to specify all of  
those, yeah.

For your specific problem here, it's less clear.  For a first cut, I'd  
probably aim for the minimum changes that you discover you need, but  
yeah, another approach would be to specify all of the packages that  

I don't know which approach will be faster.

Zope 3.3 was not eggified.

Looking on pypi (http://pypi.python.org/simple/zope.testing) it looks  
like you can try the 3.6 line, the 3.5 line, the 3.4 line or the 3.0  

If you don't get success soon, let me know what the exact traceback  
you get is, and under what exact circumstance (running your own tests,  
right?).  I might be able to suggest a specific zope.testing version.

I suspect this won't be as easy as I would like until Zope 2/Plone is  
eggified. :-/ That said, having to specify versions wouldn't be too  
bad, once the version cocktail has been determined.

I hear you.  FWIW, I can help with zc.twist if you want, but I doubt  
ZODB is going to change.
