I\'ve installed virtualenv via pip and get this error after creating a new environment:
selenium:~ auser$ virtualenv new
New pyt
I've run across this problem myself. I wrote down the instructions in a README, which I have pasted below....
I have found there are two things that work:
If you're using a non system Python as your standard Python (which python to check) Forcefully use the System supplied one.
Instead of virtualenv thing use /usr/bin/python2.6 PATH/TO/VIRTUALENV thing (or whatever which
python returned to you - this is what it did for me when I ran into this issue)
