Comment(by north@…):

 Some additional info:

 First, I fished through the comparative setups and some strange
 orientation of the planets and files left in the directory meant when
 1.7.0 built xrender, it did not pull in all the xorg-libX11 cruft; just
 xorg-renderproto. With that as a clue, I ran gdb on a little gtk app.
 Here's the output:

 (gdb) run pix/backgrounds/*.jpg

 I suspect something in the new xrender Portfile pulling in xorg-libX11 in
 Tiger/Panther might be causing a problem. If any further info can be of
 help, please let me know. It also looks like this is a Tiger/Panther
 specific issue..?
