Yes, I think testing with zope.release is a good way of doing this right now. 
I tried to verify the steps:

1. Checkout zope.release
2. Run python bootstrap.py
3. Run ./bin/buildout -N
4. Run ./bin/generate-buildout

5. cd test
6. python ../bootstrap.py
7. ./bin/buildout -N
8. ./bin/test -vpc1

I am running the tests as I am writing this. So far I got one failure:

Traceback (most recent call last):
  File "/opt/zope/packages/eggs/z3c.macro-1.2.1-py2.5.egg/z3c/macro/tests.py", 
line 29, in <module>
    import z3c.pt
ImportError: No module named pt

I'll report the full output when it is done.

It is needed for the "latest-versions" script as this parses XML. I consider 
lxml pretty much the standard tool to do XML in Python these days. Who is not 
using lxml?

Having said that, "latest-versions" is not needed by everyone all the time. I 
could live with putting it into an extra and not build the latest-versions 
script by default.
