The UPDATING entry was a different issue.

The trouble with this is that when you deinstall some prerequisite
package, that other packages might also need that prerequisite package.
So pkg_add would have to figure out that it needs to deinstall all the
packages needing that prerequisite package, and then reinstall them.
For example, you want to upgrade gnome2, which depends on libX11. But
in upgrading libX11, pkg_add has to figure out that it also needs to
deinstall openoffice, and then reinstall it.
I would think that something like this could be done, but it would be a
lot of work to write this program correctly. (But you might be
satisfied that pkg_add does what portmaster does, which is to update the
+REQUIRED_BY entries in all the appropriate places in /var/db/pkg. That
probably wouldn't be too hard.)

What I do is to use a script like this:
!/bin/sh
for p in /var/db/pkg/*; do
if [ -d $p ]; then \
p=`basename $p`
if ! [ -e $mylocaltinderbox/All/$p.tbz ]; then
echo $p
fi
fi
done
and then pipe the output of this script into
xargs pkg_delete -r
