Please read again: it is temporary workaround. At least for me. It makes my 
installed ports working *immediately* with small possibility something will 
not work at all due some ABI chabge or somesuch. Rebuilding some KDE ports 
took me couple of days (finding the way, compile etc).

The difference - works immediately vs. a week or so without working kde is 
immense.

How did you determine this is exactly the lib to look into? Just wondering...

After my symlink trick, portmaster rebuilt everything necessary, so aj could 
remove the symlink afterwards. So I think it was kind of hackish solution, 
but made my fixing *much* easier and, more important, less stressfull. That's 
it. Maybe not nice, but really effective.
