Yes, but it's manageable by separating out who controls which
installation locations.  The admin of a machine is the only one who
should be sticking stuff in site-packages, so if his users are
affected by a version conflict, he'll resolve it amongst his users.

A Python application that needs and/or provides a package should never
install it in site-packages, so it can exactly control the version it
wants.
