It may be worth noting the intent of specifying versions in a buildout
config and a version constraint for a software package in setup.py is
different.

Constraints in setup.py are intended to specify what versions a
package is compatible with; they're about the code in the package.
Versions in a buildout config (sometimes called "nails") are about
getting a repeatable build: *this* build should use exactly *this*
version.

I hope that helps.
