This needs a new package for the dependency, but until that's done, dev-python/cherrypy-18.1.0 should probably be masked.
We'll need a dev-python/namespace-zc packages (note that there's a dev-python/zc-buildout ebuild that installs the zc package).
A temporary fix is to do $ easy_install --user zc.lockfile which installs the missing package for the current user. Sidenote: there apparently used to be a zc-lockfile ebuild when net-zope was still in the tree, but that's all gone now.
zc-lockfile has since been added, and zc-buildout was removed.
