[Distutils] buildout pinning versions and egg requires

[Jeff Kunce]

Thanks Maurits (and Benji) -

That explains a lot.  We are running on windows, and our versions.cfg was
generated by buildout.dumppickedversions - it looks like everything in that
file is all lower case.  Your suggestions will be very useful.
