I'm running Ubuntu 11.10. I have both Python 2.7 and 3.2 installed on the system and available in /usr/bin/. I am looking to start using pythonbrew and it seems it will want me to install my python versions in my user directory. Do I need to do anything with the currently installed versions python? the info on pythonbrew that I can find doesn't really mention the legacy versions of python that might be installed on a system.
