Activated VENV still use system pip and system python? What's wrong?
===

When I activate a `venv`, `which pip` returns `/usr/local/bin/pip` instead of `path/to/my/apps/venv/bin/pop`. Why is that?

I am inclined to just `rm- rf` the pip in `/usr/local/bin/pip` and install again, but since this is a production server I prefer not to guess too much :-)

My concern is that I have (in usr/local/bin):

 - easy_install
 - easy_install-2.6
 - pip
 - pip-2.6
 - virtualenv
 - virtualenv-2.6

`python --version` returns 2.6.6 and `which python` returns `/usr/bin/python` even though `venv`is activated?
