Messy ports, how to clean them up?

I've always used pkg_rmleaves... pops up a nice little dialog listing all 
the ports that aren't required by any other ports... check the ones you 
want to get rid of...  on my non-serious boxes I tend to check anything I 
don't recognize and/or things I know I want gone.

Then it repeats the process with any new ports that are no longer required 
due to anything you just removed.

Seems to work pretty well for me...
