Indeed, but sadly, setuptools is case insensitive as far as
distributions go, which means that buildout ends up doing bizarre things
when different casings of the same package name are used, particularly
when it comes to pinning versions.
Yes, the "correct" thing to do would be for buildout to kick out
requirements where the case of the distribution name specified didn't
match that returned by the distribution that setuptools decided would
satisfy that requirement.
However, that would mean you'd suddenly have distributions that would
work with easy_install and pip but not with buildout.
I guess my point is that, by way of being based on setuptools, buildout
already *is* case insensitive w.r.t. distribution names and the fact
that *only* version pinning *is* case sensitive ends up being a bug...
