That's fairly general advice about MacPorts, not specific to  
installing an older version, so I don't know that it belongs in that  
particular how-to.

That's like this bug:

http://trac.macosforge.org/projects/macports/ticket/13678

You must deactivate or uninstall tk 8.5 before you can build tk 8.4.  
I think this is a peculiarity of tk.

This problem was supposedly fixed in the latest version of the  
portfile, but still exists of course in the old version of the  
portfile you're using.
