[python-uk] easy_install pip won't work, am concerned Ministry of Packaging may chase after me.

[Mike MacCana]

Thanks. I understand what you're saying, but personally I'd like to have
Ubuntu own site-packages, and have everything required for each project
installed via VirtualEnv:

- A large part of a lot of OSs (particularly Linux and OS X) uses python,
and therefore site-packages, and there's been a few cases of apps trashing
site packages that were used by the OS (this isn't Python specific, and
could just as well occur with Ruby gems if you were using puppet).

- I like the Ubuntu security updates and knowing everything outside my own
development environment is taken care of

- My app can still get whatever it wants inside the virtualenv, and I have
the ease of deployment associated with having and independent site-packages.

Cheers (and thanks again for your help),

Mike
