Second, if the file name of a distribution doesn't match the

Setuptools doesn't "import" ZopeInterface or TwistedWeb - it looks for

I'm not an expert on setuptools, I'm just guessing what it does based on behavior. Maybe this is explained somewhere in the web pages, sorry I often neglect to thoroughly read documentation. However, I did read that setuptools only supports distutils-based distributions, I was trying to ask if there were ways around this. I'll take this as a unqualified "no".

In any case, 4/5 of my dependencies are for one reason or another not compatible with setuptools. I'll ask them to change their ways, in any I'm sure this battle will be easier to fight once setuptools is part of the standard python distribution. I thought was slated for python2.5, but I've checked the release notes and I don't see mention of its inclusion.
