More frustration...
the EOModeler of Alex was done in an old OS X version and uses some methods which had been deprecated in 10.4 (e.g., the NSFont method - (CGFloat)widthOfString:(NSString *)aString); even though it compile in Tiger, it does not in Leopard. So, I will have to debug his code and "repair" it before I can compile-and-run it into Leopard.
