Patrick Gerken suggested that I reconfigure this buildbot to use
mode='clobber' to flush out latent issues, and, well, issues came out:

    $ virtualenv -p python2.4 --no-site-packages sandbox
    $ sandbox/bin/python bootstrap.py
    $ bin/buildout
    $ bin/generate-buildout
    $ cd test && ../bin/buildout
    While:
      Installing.
      Getting section test.
      Initializing section test.
      Installing recipe zc.recipe.testrunner.
    Error: There is a version conflict.
    We already have: setuptools 0.6c12dev-r84273

on all four buildslaves.

(Oh how I wish buildout produced *useful* error messages.)

I have a hunch this is due to virtualenv 1.3.3, which is installed into
/usr/local/bin/.  I've tried upgrading virtualenv to 1.4.5 (the version
in Ubuntu 10.04) and the error now is

    $ virtualenv -p python2.4 --no-site-packages sandbox
    $ sandbox/bin/python bootstrap.py
    $ bin/buildout
    $ bin/generate-buildout
    $ cd test && ../bin/buildout
    While:
      Installing.
      Getting section test.
      Initializing section test.
      Installing recipe zc.recipe.testrunner.
    Error: There is a version conflict.
    We already have: zc.buildout 1.5.0

Looks like the outer buildout.cfg doesn't pin zc.buildout so it always
gets the latest version, and the inner one doesn't like that at all.  I
think the fix is to change buildout steps to do this instead:

    $ virtualenv -p python2.4 --no-site-packages sandbox
    $ sandbox/bin/python bootstrap.py
    $ bin/buildout
    $ bin/generate-buildout
    $ cd test && ../sandbox/bin/python ../bootstrap.py && bin/buildout
    $ bin/test
