I don't know what you mean here. I don't recall managing any .pth 
files... If I add addsitedir to the right places, the eggs will be 
picked up. I have a test egg for the Document Library here that pulls in 
pyoai, lxml (dependency of pyoai), hurry.query, zc.catalog (dependency 
of hurry.query), hurry.workflow, and hurry.file.

If I include the right ZCML in package-includes, Document Library works.

I hope to start using zc.table and its dependency (zc.resourcelibrary) 
eventually as well. It's nice I can do this with just a tweak to the 
Document Library's setup.py and a new ZCML include.

I'm just distributing a script that tosses this into any given Zope 3 
instance now, so people can at least use this stuff in Zope 3.3. And 
yes, there's too much magic going on, and I hope zc.buildout will make 
life easier and less magic on the longer term.
