In my django project I was trying to use vobject and had installed it through
easy_install vobject
But vobject uses dateutil=>1.1, so easy_install automatically installed dateutil 2.0
The problem is that dateutil 2 only supports python 3.x
So to solve the problem, I had to get dateutil < 2.0
Fix:
sudo easy_install dateutil==1.5
This also will work in your django buildout.cfg
eggs = dateutil==1.5
vobject
