pkg_delete -i "*"

This should refuse to delete packages with dependencies even if you
respond yes. Of course I didn't test this :)

I've taken to packaging everything I build from ports. This way
you can just do...

pkg_delete -a

	...then pkg_add from the built copies.

You'll see the advantage if you ever build KDE from ports (18hrs for
me!).
