Tarek, correct me if I am wrong here, but 3rd party tools will need to
rely on distribute(setuptools) as packaging/d2 will never provide a
backwards compatible substitute or API. Packaging/d2 relies on
distribute as an external dependency.

So in this case buildout2 will need to support distribute and later
add support for packaging down the road.

So buildout2 will need packaging/d2 + distribute.
