Why am I unable to launch MATLAB on my Intel Mac OS X 10.4 machine?

When I launch MATLAB, X11 starts but MATLAB never comes up. If I launch MATLAB from an xterm window, I receive the following error message:

 dyld: Library not loaded: /usr/X11R6/lib/libXext.6.dylib

    Referenced from: /Applications/MATLAB74/bin/maci/MATLAB.app/ 

 Contents/MacOS/libmwhg.dylib

    Reason: no suitable image found.  Did find:

          /usr/X11R6/lib/libXext.6.dylib: mach-o, but wrong architecture

 Trace/BPT trap

This error message indicates that you have the PowerPC version of Apple's X11 installed on your Intel machine. In order to resolve this problem, please reinstall X11 from a set of Tiger DVD's for the Intel MAC architecture.
