'zc.buildout-2.3.0 ()' is being parsed as a legacy, non PEP 440,
version. You may find odd behavior and sort order. In particular it will
be sorted as less than 0.0. It is recommend to migrate to PEP 440
compatible versions.
Actually, I have configured zc.buildout to use a download-cache
directory where it saves downloaded zips/tarballs/eggs from PyPI.
Buildout then adds this directory as a find-link and setuptools calls
package_index.scan_url on it. This prints the warnings, because it sees
for example a file
'/Users/mauritsvanrees/cached-downloads/dist/Acquisition-2.13.8.zip'
This gets parsed as a Distribution with project_name
'Acquisition-2.13.8' and an empty version.
Ah, a demo with plain setuptools 0.8.4 is easy to setup:
$ mkdir bar
$ touch bar/project-1.0.zip
$ . bin/activate
(venv) $ python
Python 2.7.8 (default, Jul 28 2014, 10:41:45)

>>> pi = package_index.PackageIndex()
