One thing to note: as developers are more and more keeping their
programs totally inside of the application bundle, the problem you are
referring to (i.e. two different programs installing the same "Y"
thingy in /usr/local/bin/) is becoming less and less of a problem for
un-installers to ponder, which is actually a very good thing as this
same problem has never been completely dealt with in the *nix world.
