Yes.

What's there to stumble over if it's hidden? Just put it on your 
svn:ignore list and move on.

This is not a zc.buildout problem. zc.buildout is a general purpose 
deployment tool and not specific to Zope 3. I've seen people mix this up 
several times now, so I thought I'd restate this to make it absolutely 
clear.

Now, what you mention *is* a real problem, though. If packages depend on 
other packages' configuration, they should include this configuration 
themselves as well (the ZCML machinery will make sure that files aren't 
executed twice). This is something that I hope to fix at one of the 
upcoming sprints (we have one planned specifically dedicated to sorting 
out package dependencies and things like that).

In the mean time, I suggest looking at the project template that 
zopeproject generates. It may provide some pointers.
