Interestingly, on R 1.9.0 and MacOS 10.3.4, I was just able to install rgl without problems this morning. Is this perhaps an issue with movement from 10.2 to 10.3, as I know the X11 stuff changed quite a bit. (I have to admit that I haven't been following this thread closely, but just wanted to point this out.)
