title: Why am I getting this simple error when using `acts_as_taggable_on`?
body: <p>I wanted to set up <code>ActsAsTaggableOn.strict_case_match = true</code><br>
  According to <a href="http://5minutenpause.com/blog/2012/11/20/careful-where-you-get-your-gems-from/" rel="nofollow">http://5minutenpause.com/blog/2012/11/20/careful-where-you-get-your-gems-from/</a>, it seems I have to download the gem from github. So I made it that way and tried to run App.</p>
  
  <p>However, it returns this error:(</p>
  
  <p><strong>Error message:</strong> (I've tried <code>bundle install</code> but still the same error message!)</p>
  
  <pre><code>git://github.com/mbleigh/acts-as-taggable-on.git (at master) is not checked out. Please run `bundle install` (Bundler::GitError)
  Exception class:
      PhusionPassenger::UnknownError

  <hr>
  
  <p>Here are my codes!</p>
  
  <ul>
  <li><p>config/initializer/tag_list.rb</p>
  
  <p><code>ActsAsTaggableOn.delimiter = ','</code><br>
  <code>ActsAsTaggableOn.remove_unused_tags = true</code><br>
  <code>ActsAsTaggableOn.strict_case_match = true</code>  </p></li>
  <li><p>Gemfile</p>
  
  <p><code>gem 'acts-as-taggable-on', git: 'git://github.com/mbleigh/acts-as-taggable-on.git'</code></p></li>
  </ul>
  
  <hr>
  
  <p>I made a try to change the source to download the gem directly from to rubyorg, not from the Github. It's just like this.</p>
  
  <pre><code>gem 'acts-as-taggable-on', '2.3.3'
  </code></pre>
  
  <p>Now it returns this error:(</p>
  
  <p><strong>Error message:</strong></p>
  
  <pre><code>undefined method `strict_case_match=' for ActsAsTaggableOn:Module
  </code></pre>
  
  <p>How can I solve this?</p>
