Python pip on Ubuntu Lucid Lynx

Lately I’ve been reading up on Django a bit in an effort to get back into programming. It seems the preferred way of running Django is inside a virtualenv environment. I try to stick to packages when possible for installing applications and saw that the python-virtualenv package wasn’t too far behind at version 1.4.5, where the latest is at 1.5.1. This appeared at first to suit me just fine until I discovered the version of pip that gets installed along with python-virtualenv is at 0.
