Yes, re-install X11. You failed to supply any details so we can only  
speculate, but my guess would be that you upgraded from ppc to intel  
at some point (or installed some other X11) and thus your X11 doesn't  
have intel binaries. But, again, without any details (sessionInfo(),  
machine type and preferably output of "file /usr/X11R6/lib/ 
libX11.6.dylib") it's only a wild guess.
