Help latest pip and old setuptools to work together.

The latest version of pip doesn't play nicely with the ancient
version of setuptools which comes with Debian - it requires
setuptools 0.8, and we only have 0.6.

In order to fix this, we use a script get_pip.bash from commonlib
to securely install pip and then update to a nice new setuptools.

It looks like this is going to be fixed in version 1.5.1 of pip:
