Done :) with the caveat expressed in
http://mail.python.org/pipermail/distutils-sig/2013-January/019622.html
 as I am using underscores as separators rather than dots:
See : https://github.com/pombredanne/buildout/commit/44902dcc5ac9306db1a8a26fa92ff3a761029b0e

The pull request contains this, with new tests
https://github.com/buildout/buildout/pull/51

and all tests are passing  (or failing the same way they do with a
standard buildout 2.0 for Python 3.2)
