Could you explain how the find-link would work with an ==dev version 
specification?

Again, this may be a buildout issue, but I have:

  find-links =
     ...
 
http://svn.plone.org/svn/archetypes/archetypes.kss/trunk#egg=archetypes.kss-0.1dev
     ...

  eggs =
     ...
     archetypes.kss==dev
     ...

This gives me an error:

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

I have a feeling this means my find-link is wrong, but I couldn't find a 
permutation that works...
