An egg should only *depend* on setuptools if it uses things like 
pkg_resources (e.g. for namespace packages). In that case even 
zc.buildout yells at you for not depending on setuptools:

   zc.buildout.easy_install: Develop distribution for kss.core
   0.1dev-r37968 uses namespace packages but the distribution does not
   require setuptools.

That setuptools are required for *building* an egg goes without question.
