Please post the output of

file /usr/X11R6/lib/libX11.6.dylib

you should see something like

$ file /usr/X11R6/lib/libX11.6.dylib
/usr/X11R6/lib/libX11.6.dylib: Mach-O universal binary with 3 architectures
/usr/X11R6/lib/libX11.6.dylib (for architecture x86_64):	Mach-O 64-bit dynamically linked shared library x86_64
/usr/X11R6/lib/libX11.6.dylib (for architecture i386):	Mach-O dynamically linked shared library i386
/usr/X11R6/lib/libX11.6.dylib (for architecture ppc7400):	Mach-O dynamically linked shared library ppc

if your X11 is installed properly.

Thanks,
Simon
