Subject: Wrapping a C Library: Allocation and duplication issues

I'm writing a wrapper for a C library [1] written in a very object 
orientated style.  All of the "classes" are created with a 
librdf_new_classname method which acts almost the same as Ruby's 
Class#new.

The problem I'm having is cleanly separating allocation from 
initialization.  Since most of the class construction functions require 
arguments to initialize the object, I can't define separate alloc and 
initialize functions.

The only option I see is to use Ruby 1.6 style code and define a 
Klass.new method for my classes.  The problems with this is it prevents 
clean subclassing and object cloning.  Is there a better way to wrap the 
library?

Thanks,
Justin
