I can't tell you the exact SVN version, but as of Dec 4th, I have a  
build of the OSX frontend on Tiger.  I made pretty much all of the  
changes you did but I'm not using ccache that I'm aware of.

The Xinerama stuff at least, will be contained in /usr/X11R6/lib/ 
libXinerama.dylib.  The others are stuff like QComboBox, which look  
like QT stuff. (It looks like you have qt-mt linked though, so you  
may want to go down that road a little further.

Hope this is of some help.  I'm not home for a month, otherwise I'd  
look at my build environment a little.
