Yes that worked. Thank you for the very informative reply!

gtk2 was the issue. As a follow-up question: for some reason, I have  
both gtk1 and gtk2 active. Is there any reason to have both? In other  
words, why might I have gtk1 active? I certainly did not install it  
directly. I mean I understand that ports can be installed as  
dependencies, but is there some port(s) that requires gtk1 over gtk2?  
Is there a port command to tell me which ports may have required it?

   gtk1 @1.2.10_6 (active)
   gtk2 @2.12.9_0+x11 (active)
