You don't need the py25-tkinter port anymore due to recent changes in  
python25. I should note that in the ticket - or better yet, make a  
wiki page about this. Make sure you have the latest python25 portfile  
(with "sudo port selfupdate"). In any event, you will have to rebuild  
your python port after installing tcl/tk 8.4.


Cheers!
Frank
