[Zope] Using eggs in a Zope instance

[Anton Stonor]

Python eggs are fun and powerful. However, there is one thing I can't 
get right when using them for Zope projects:

Sometimes I would like eggs to live in $INSTANCE/lib/python instead of 
site-packages. E.g. if different instances needs different versions of a 
package.

However, easy_install won't install them there, because 
$INSTANCE/lib/python is not in the PYTHONPATH.

And I don't want to extend PYTHONPATH to include all my 
$INSTANCE/lib/python's -- that would prevent the different version pr. 
instance approach.

How does you egg front runners deal with this?

I'm on Windows if that matters.
