Subject: C extensions using Singleton

Another C extension question for the experts: in a C ruby class, I'm 
trying to use the Singleton standard library.  It doesn't work, though 
no errors are thrown.

  ruby_rpg_class = rb_define_class("RPGEngine", rb_cObject);
  rb_require("singleton");
  rb_include_module(ruby_rpg_class, rb_const_get(rb_cObject, 
rb_intern("Singleton")));

With this C code above, I can still call RPGEngine.new and get a new 
instance of the class.  RPGEngine.instance throws a NoMethodError.

Is the code above correct? 

Thanks again,
