I am not sure why you don't want to hear from me!

The answer to your problem is very simple:
The error message is from Tk which is trying to create a Window on  
the X11 display.  Unlike other forms of UNIX/Linux MacOS X does not  
use X11 for its normal display.  So before trying to run X11 code you  
must start X11 by double clicking the app in /Applications/ 
Utilities.  If you have not started it Tk will barf.

If you are using X11 a lot, you may want to go to System Preferences - 
> Accounts and set it to autostart for your login.

Hopefully, sometime real soon now, BLT 3.0 will ship with proper  
MacOS X Aqua support and we won't need X11 at all.
