More than one version of a port installed.

[David Epstein]

On doing port installed, I found many examples like this:
tcl @8.5.4_0
tcl @8.5.5_0 (active)

The first would not allow an uninstall because of dependencies. Is there
anyway to reasonably clean up the situation so that I end up with only one
version (the latest) of each port? But I suppose that wouldn't work because
some port may insist on a particular outdated version of a package it
depends on. So what's the best one can do in this direction with not too
much manual work?

By the way, I installed the most recent version of port, so any advice
should be in the light of that. I enjoyed the fact that port selfupdate no
longer produces large amounts of seemingly irrelevant output. Very nice and
clean. Thanks so much for all the work---much appreciated.
David
