Then why don't you get a checkout if the other stuff troubles you so  
much? In my very first response to you I wrote:

"Of course you can get a checkout of any package you wish from  
svn.zope.org, including the zc.* packages. However, they'll likely  
have dependencies which you will have to resolve as well."

I think those a very clear instructions: get the package you want  
from subversion and also get its dependencies so that it works.  
What's the problem?

I'm not sure what "working in the zc.buildout" is supposed to mean. I  
don't consider zc.buildout evil. Not totally at least :).
