The issue you encountered is a side effect of the different style of  
the X11 installation under Leopard, specifically the location of the  
color database rgb.txt.  I made some changes to circumvent that issue  
entirely, and also made an adjustment to accommodate file and  
directory names with spaces.  You can download the latest version from:


NB: The name of the script as downloaded might be diffps.sh -- feel  
free to remove the extension.
