[Distutils] why this version spec does not work?

[Adam GROSZER]

Hello,

I have here this version spec in setup.py:
'zope.testing >=3.6.0,<3.10.0',

but zc.buildout does not get it right.
Source is here:
svn://svn.zope.org/repos/main/zc.recipe.testrunner/branches/1.2.1
Output is here:
http://paste.lisp.org/+2FSQ

Why on earth does zc.buildout pick zope.testing = 3.10.0 with the
above spec??
