Is there a way to compare what is in the ports tree with what is installed?

[Brett Davidson]

ie. If I had a particular version of the ports tree on a server, how 
could I check to see if any of the programs in that tree were actually 
installed?

Is there a simple command or sequence of commands to do this?
