Subject: require not working correctly?

I'm just starting out in Ruby, and I used the one-click installer. The
version on my computer seems to be Ruby 1.8.6-27.

I'm working through some of the examples in Why's Poignant Guide, and
things seem to have broken down here:

File wordlist.rb contains:
puts 'Wordlist got required'
code_words = {
   'starmonkeys' => 'Phil and Pete, those prickly chancellors of the
New Reich',
   'catapult' => 'chucky go-go', 'firebomb' => 'Heat-Assisted
Living',
   'Nigeria' => "Ny and Jerry's Dry Cleaning (with Donuts)",
   'Put the kabosh on' => 'Put the cable box on'
 }

File script.rb contains:
require 'wordlist'
# Get evil idea and swap in code words
puts "Enter your new idea: "
idea = gets
code_words.each do |real, code|
  idea.gsub!(real, code)
end
# Save the jibberish to a new file
puts "File encoded. Please enter a name for this idea: "
idea_name = gets.strip
File::open("idea-" + idea_name + ".txt", "w") do |f|
  f << idea
end

This is basically copied out of the Poignant Guide, with the addition
of the puts method at the start of wordlist.rb.

Both are in the same directory. I navigate to that directory in cmd,
and then type ruby script.rb

It prints Wordlist got required, then prompts for an evil idea, and
after I hit enter, gives the following error:
script.rb:5: undefined local variable or method `code_words' for
main:Object (NameError)

What am I doing wrong?

Thanks,
