title: Gem not outputting the expected text
body: <p>I've completed the <strong>First Gem</strong> section of <a href="http://guides.rubygems.org/make-your-own-gem/" rel="nofollow noreferrer">this tutorial</a>. However, in the <strong>Requiring More Gems</strong> section when I tried modifying my hola.rb as such:</p>
  
  <pre><code>class Hola
    def self.hi(language = :english)
      translator = Translator.new(language)
      translator.hi
    end
  end
  
  require 'hola/translator'
  </code></pre>
  
  <p>and added this translator.rb file:</p>
  
  <pre><code>class Hola::Translator
    def initialize(language)
      @language = language
    end
  
    def hi
      case @language
      when :spanish
        "hola mundo"
      else
        "hello world"
      end
    end
  end
  </code></pre>
  
  <p>If I typed in these commands in IRB, I should get identical outputs:</p>
  
  <pre><code>% irb -Ilib -rhola
  irb(main):001:0&gt; Hola.hi(:english)
  =&gt; "hello world"
  irb(main):002:0&gt; Hola.hi(:spanish)
  =&gt; "hola mundo"
  </code></pre>
  
  <p>However, I'm not getting proper results. I tried modifying my gemspec and reinstalling the gem, but no success. What do you think I did wrong in this case?</p>
  
  <pre><code>stanley@ubuntu:~/Github/webdev_class/ruby/hola_stanley/lib$ irb -Ilib -rhola
  irb(main):001:0&gt; Hola.hi(:english)
  =&gt; "hello world"
  irb(main):002:0&gt; Hola.hi(:spanish)
  =&gt; "hello world"
  irb(main):003:0&gt; quit
  </code></pre>
