Hi Giampiero, The warning messages are due to virtualenv creating a folder “lib” and a link “lib64” that links to “lib”. Both these library paths are put onto sys.path, so to Zope it looks like there are two distinct locations containing the same Zope products.
Installing Zope products into a virtual environment with pip isn’t very common. Most users and most developers/maintainers use zc.buildout to create Zope instances with buildout recipe plone.recipe.zope2instance.
