This is, quite frankly, ridiculous, and not just because of Windows.
So, say I produce a binary egg for mysqldb, pip's position appears to be
that I'm wrong, and I should have to make sure all the build
dependencies are present on my whole cluster of identical machines.
Same goes for lxml, and anything else with complex build dependencies.
Really, wtf? ;-)

Right, so I guess I'm back to buildout...

Hmm, but it's not there yes, and it is with buildout...

Yeah, I think this is just a style thing :-)
