I think I understand.

RBApplicationMain will parse the command line arguments as if they  
were arguments to the Ruby interpreter. If you wish to avoid this, you  
can use RBApplicationInit instead, and take responsibility for calling  
NSApplicationMain youself.  In other words, change your main routine to:

int main(int argc, const char *argv[])
{
   RBApplicationInit("rb_main.rb", argc, argv, nil);
   return NSApplicationMain(argc,argv);
}

This should invoke rb_main (without parsing the arguments as Ruby  
arguments) and then begin the application as normal.
