Require error on usage example with deltacloud-1.3.3

[John B. Wyatt IV]

Greetings,

I get this error from the example on the usage page.

....rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in
`require': cannot load such file -- deltacloud (LoadError)
    from
.....rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in
`require'
    from digitalocean.rb:4:in `<main>'

To install deltacloud I used
gem install deltacloud-client

I'm trying to learn how to use deltacloud to manage a Digital Ocean account.

Here's the source
#require 'rubygems'
require 'deltacloud'

# this intializes a mock server
api_url      = 'http://localhost:3001/api'
api_name     = 'mockuser'
api_password = 'mockpassword'

client = DeltaCloud.new( api_name, api_password, api_url )
