Thanks to Phillip for the insight into the interaction between command-line arguments and options. So another question regarding error reporting. When I so something like:

$ PYTHONPATH=lib/ python ez_setup.py --install-dir lib/ --script-dir bin/ --site-dirs lib/ zope.testing

setuptools is bootstrapped correctly, and zope.testing and its dependencies are downloaded and installed. However, at the end of the run you get a message like:

Installed /home/nathan/Projects/zope.i18n/lib/setuptools-0.6b1-py2.4.egg Processing dependencies for setuptools==0.6b1 error: None

Does anyone have any insights into this?

Okay, I finally tracked this down. It's actually the same error as the: "error: No urls, filenames, or requirements specified (see --help)" message you were getting before. Or rather, they're both caused by a freaky code fallthrough bug in ez_setup.py. If, and only if, you are installing setuptools when it is not available on the local system, ez_setup tries to run easy_install *twice* with more or less the same arguments. If you do *not* have any non-option arguments, you will get the first message. If you *do*, then easy_install gets an IOError because it tries to read from the temporarily-downloaded setuptools.egg that has already been deleted. The distutils sees this IOError and unhelpfully (not to mention idiotically) outputs "error: None" and aborts! So I've fixed the source of both problems in the SVN trunk, and the 0.6b3 release (probably today) will have an ez_setup.py with the fix.
