The R build is compiled with 2), but using 1) should work, too. Both  
compilers seem to mix well, but make sure you use the corresponding  
gfortran if you plan on using Fortran code. Just don't use any other  
compilers (fink, HPC, ...) - they don't work properly.

3) use official X11 release from Leopard

The R build is built against Apple's release Leopard X11. I have not  
tried 1), so I can't comment on it (AFAIR Tiger's X11 doesn't have 64- 
bit support). In either case 2) and 3) you have to fix the libGL bug.  
I was running 3) successfully and have updated to 2) just for testing,  
either works fine.
