Eggs, both the zipped up versions as well as unzipped directory versions
are containers for packages, more akin to directories than python
packages or modules. Setuptools adds .egg files/directories to your
sys.path directly (typically using something like an easy-install.pth

Right, because your sys.path doesn't list a directory full of packages,
it lists a directory full of eggs (e.g. directories).

Yup. You *really* want to be using virtualenv. Apache's mod_wsgi
that, you might want to try using .pth files in your system path to
augment your search list (see the docs for 'site' module for details
on .pth files) to include the paths to your .eggs. Still, the virtualenv
is a much cleaner (and altogether more supportable) solution.
