Is /opt/local/var/db/dports still used?

[Joe Davison]

Recently, when I did the selfupdate (to version 1.6?) on one of my  
machines, I got a message saying some stuff may have been left in / 
opt/local/var/db/dports... in the move to ...var/macports and I  
should take care of it myself.

That message could be a bit clearer -- is it the case that the entire  
directory tree below /opt/local/var/db is no longer used, and I can  
safely  rm -rf  on  that directory?
