Alas, this gives me this error:

Traceback (most recent call last):

ValueError: ("Couldn't find", Requirement.parse('archetypes.kss==dev'))

Is there something else I need to do to the svn repository 
(http://svn.plone.org/svn/archetypes/archetypes.kss/trunk)? Or is this a 
zc.buildout limitation?
