I've been getting strange behavior with trying to use Buildout with setuptools pinned to 0.6c11 on Mac OS X 10.6, with Python 2.4 built from MacPorts. I'd constantly get the following error:

Getting distribution for 'zope.interface==3.5.2'. No eggs found in /var/folders/ta/taVYwGZqHuKHt5V7rcwEzE++-+s/-Tmp-/easy_install-7kLZlO/zope.interface-3.5.2/egg-dist-tmp-dC9GYL (setup script problem?)

I first noticed it when trying to use a fresh 'bootstrap.py' from zc.buildout (which I have traditionally not used in our projects), and tried the 'Use Distribute' option. What was interesting was that `zope.interface` 3.5.2 was already installed in my eggs directory, and buildout should not have been trying to get a new one.

So this problem seems to show up with both Distribute (0.6.8?) and setuptools (0.6c11).

Pinning setuptools to 0.6c9 does not have this problem.

I don't know if this is related, but when comparing the setuptools 0.6c9 and 0.6c11 source trees, I noticed a change in how the Mac OS X version is looked up:

Yep, that would cause the problem you're showing above. I'll make a note to change the version check code to fall back if mac_ver() gives spurious results.
