It's still plain old gcc 4.0 (4.2 should be an option soon), but they  
have an
entirely new ld which can't handle text-relocations in shared objects.

The fastest way to get it fixed is probably to file duplicates of my  
bug #5578031
on Apple's reporter, or use the 10.4 SDK.

(It has some other problems too, like using the provided X11's  
freetype for subtitles in mplayer)
