Huh?  Entry point script wrappers *set* __requires__ as the very first
thing they do, followed by importing pkg_resources.  (Alternatively,
if you build the scripts using buildout, they have paths hardcoded.
Either way, no problems with default versions.)

The only way I can see problems is if you *aren't* using entry point
wrappers for your scripts, *and* you want non-default versions.

Indeed.
