How do I remove/delete a virtualenv?

I created an environment with the following command: virtualenv venv --distribute

Trying to remove it with the following command: rmvirtualenv venv does not work.

I do an lson my current directory and I still see venv

The only way I can remove it seems to be: sudo rm -rf venv

Note that the environment is not active. I'm running Ubuntu 11.10. Any ideas? I've tried rebooting my system to no avail.
