Well it looks like your virtualenv is installed with easy_install (inside an egg) whereas mine was done with pip. My suspicion is that this is the cause of the problem - somehow that location is on the path for the Python 3 environments.

My version of virtualenv is 1.6.4. Are you sure you're using Python 2.7? The default on OS X 10.6 is Python 2.6. (I'm using OS X 10.7 but I think the location of virtualenv is more likely to be the problem.)

All the best,

Michael Foord

May you do good and not evil
May you find forgiveness for yourself and forgive others
May you share freely, never taking more than you give.
