Following code may be available for your purpose. But such conding
is almost no tested currently. I am not confident about this code
work.

  const char* ruby_script = "class Hello;def sayHello() \"Hello\" end end";
  id hello = [[NSClassFromString(@"RBObject") alloc] initWithCStrig: ruby_script];

You are right. I think that my decision which removed
RubyCocoa.framework from RubyCocoa 0.3 was a mistake.

I have a plan for RubyCocoa 0.4. Almost RubyCocoa code and libruby
will be implemented as RubyCocoa.framework. This framework will be
able to use directory or through osx_objc.bundle.

thanks, first e-mail for this mailing list :-)
