None of the above. What is the harm of the dependencies?

If it is because Zope 2 includes many of the same packages outside of  
eggs, then this is a Zope 2 problem, not a buildout problem.  This  
particular issue has been discussed a number of times.  The solution,  
short of eggifying Zope 2, is to add egg-info directories to Zope 2 so  
that setuptools can see that the dependencies are already satisfied.

If it's because extra dependencies annoy you, I'm unmotivated.
