Yes, I'm well aware of the difference between them.

You forget that the search path for both installs is different, and
hence modules installed for python-3 cannot be found/used by scripts
using python-2; which results in the dependency hell; which was the
basis for my whole argument.

The user would rather just edit the shebang for an hour rather than
become root, eselect and get back. Only us weird system-fudgers always
have a root shell running, most people rarely do.

You're twisting what I mean. You know what I mean -- packages
*needing* python-3.
