Well perhaps my problem is that I was following the documentation I 
found at rubycentral. ;)

They have, under the section called "Embedding a Ruby Interpreter," 
this exact code snippet:

#include "ruby.h"

main() {
  /* ... our own application stuff ... */
  ruby_init();
  ruby_script("embedded");
  rb_load_file("start.rb");
  while (1) {
    if (need_to_do_ruby) {
      ruby_run();
    }
    /* ... run our app stuff */
  }
}

Of course, this will NOT work, as several of you have pointed out, as 
ruby_run will exit. Ah well.

Anyway, I can just use the rb_eval-type functions to get what I want 
(which is using ruby as an embedded scripting language). 

I just thought I should have been able to get a published example to 
work. ;) Is this something that used to work but has changed? Or is 
this just a bad example? (=
