[Distutils] Path problem with zope.testing and buildout

I'm not entirely sure this is the right place to report this problem,  
but I'll give it a shot anyway.  I'm sure this is pebkac but I haven't  
figure it out yet.

My current Mailman 3 code is buildout-based.  The branch is here:

https://code.launchpad.net/~mailman-coders/mailman/3.0

Here's my buildout.cfg file:

- -----snip snip-----
[buildout]
parts =
     interpreter
     tags
     test
unzip = true
develop = .

[interpreter]
recipe = zc.recipe.egg
interpreter = py
eggs =
     lazr.config
     lazr.delegates
     locknix
     mailman
     munepy
     storm
     zope.interface

[tags]
recipe = z3c.recipe.tag:tags
eggs = mailman

[test]
recipe = zc.recipe.testrunner
eggs =
     mailman
defaults = '--tests-pattern ^tests --exit-with-status'.split()
# Hack in extra arguments to zope.testrunner.
initialization = from mailman.testing.layers import ConfigLayer;
     ConfigLayer.hack_options_parser()
- -----snip snip-----

If I build this out and then run bin/test, my test suite passes, but I  
get ImportErrors for every dependent egg that gets downloaded.  It's  
as if the eggs directory is being search for tests even though  
eggs=mailman is in the [test] section.

However, if I put the following in my ~/.buildout/default.cfg, I don't  
those ImportErrors, presumably because the eggs are so far distant  
that Zope's testrunner doesn't find them.

- -----snip snip-----
[buildout]
eggs-directory=/Users/barry/.buildout/eggs
download-cache=/Users/barry/.buildout/download-cache
- -----snip snip-----

Here's an excerpt from the bin/test output (with extra blank lines  
suppressed):

The same behavior occurs on Linux.

Does anybody have any suggestions for making bin/test work without  
putting your eggs outside the source tree?  Or if it's not possible,  
I'll update my README.txt to explain that you have to have a  
~/.buildout/default.cfg.

Thanks,
Barry
