Sorry, I don't agree. It is *never* a good idea to install packages 
globally. Using virtualenv or similar (buildout, etc) gives you a 
single, cross platform way of not ending up with a mess of a python 
installation where you have a bunch of libraries of random versions 
installed, often with no way of finding out what version they are or how 
to uninstall them.

Heaven forbid you want to use or develop more than one project per 
machine; then you end up with different projects needing different 
versions of the same libraries and you're screwed. ;-)

Ask the pip maintainers whether they'd suggest using pip on the global 
system python or inside a virtualenv...

"Python" should be though of as the application, not any individual

It isn't a lot of work from what I remember, I just don't like 
encouraging bad practices...

What is "the Python packaging" you refer to?

I would avoid both of these like the plague, it's a shame the people who 
dumped them on PyPI don't put up a similar warning :-(
