You are right. The index only works with easy_install and I did not create it, as it does not seem to be needed any more.

Yes, I just updated it to render the new version numbers.

These versions are really old. You could try to omit `--no-binary zc.recipe.egg` from the command line shown above and see if this is successful. (`--no-binary zc.recipe.egg` is needed because otherwise modern pip versions think that zc.recipe.egg is an egg and not the name of a package. I don’t know what older pip versions without support for wheels do in this case.)

This would be the first step I’d suggest: update the used virtualenv package and create a new virtualenv to install Zope there.

Distribute is dead nowadays all its changes have been merged back into setuptools. It is no longer needed/suggested to use distribute.

When you create a virtualenv with a current version of the package it automatically installs a recent version of pip.

I don’t understand what you want to switch to setuptools.
