Subject: Cookbook example - uninitialized constant

Cross posting this from Ubuntu forums

I recently got the excellent Ruby cookbook and scanning through quickly 
seized upon the Blinkenlights examples.

However I'm seeing something like this:
./blinkenlights.rb
./blinkenlights.rb:7: uninitialized constant BlinkenLights (NameError)
from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:27:in 
`require'
from ./blinkenlights.rb:4


whenever I try to execute the script
#!/usr/bin/ruby

require 'rubygems'
require 'blinkenlights'

#Turn individual lights on and off
BlinkenLights.open do |lights|
lights.left = true
lights.middle = true
lights.right = true

lights.scr = false
lights.cap = false
lights.num = false
end

#Dislay a light show
BlinkenLights.open do |lights|
lights.left_to_right
10.times{ lights.random }
lights.right_to_left
end



I'm on Ubuntu 6.06 LTS and I have the Blinkenlightsgem installed, I used 
sudo gem install blinkenlights and can list my local gems and see it.

So why do I get this error?
