title: Could not find phantomjs
body: <p>Getting the following error when trying to use phantomjs from ruby on Ubuntu:</p>
  
  <pre><code> Failure/Error: visit root_path
   Cliver::Dependency::NotFound:
     Could not find an executable ["phantomjs"] on your path.
   # ./spec/features/search_spec.rb:17:in `block (2 levels) in &lt;top (required)&gt;'

   # ./spec/support/vcr.rb:23:in `block (2 levels) in &lt;top (required)&gt;'
  </code></pre>
  
  <p>phantomjs was built locally and added to PATH. How do I make ruby find phantomjs?</p>
