Multiple complications at the same time. The new buildout was stricter 
than the old one with constraining dependencies to the right version.
For instance when installing dependencies for extensions.
mr.developer depends on buildout and setuptools.
Constraining them to the right version fails if the buildout was 
bootstrapped with a different buildout/setuptools version...

Extra complication was that installing extensions happens BEFORE 
checking if setuptools/buildout needs upgrading/downgrading :-)


The pull request also solves a problem with recipes that themselves have 
dependencies.
pdp.recipe.noserunner depends on nose, which can be installed globally. 
If that's the wrong version, you get an unclear version conflict.

With the pull request, buildout will ignore that conflict and instead 
will forcefully install the right version. This only happens when 
installing buildout/setuptools/extensions/recipes, though, not with the 
regular install/dependency handling.
