Ok, 2.2.4 is out with the fix in.

A colleague came to me this morning, however, with a problem. Ouch, it 
isn't completely fixed yet!

Turns out the `env.best_match(req, ws)` fails on anything that is 
installed globally with a version that doesn't match the one we want.

In my colleague's case, he has nose 1.3.1 installed globally.
Buildout has a pin on 1.3.4.
env.best_match() returns a VersionConflict.

So it seems we should ignore that too.



**But**, this means buildout just gained the ability to use globally 
installed packages! Hurray, I don't need
https://pypi.python.org/pypi/syseggrecipe anymore!

I can imagine that was not quite the effect we wanted!
I'll dive in a bit deeper.
