It works somewhere between "quite often" to "nearly all
the time".  It can vary depending on the complexity of
the ports you have installed, what state the tree is in,
how much the ports you use are often used by others, and
subtle differences in changes to port dependencies.

This is complex enough to be indistinguishable from "phase
of the moon."

In this case I really wish I were joking.
