title: Cucumber can't find steps when running a single feature
body: <p>I've just installed cucumber into a new rails project (first time setting it up from scratch) and it works wonderfully when running all tests (<code>bundle exec cucumber</code>) but can't find any of my steps when I run a single feature file. How might I start to debug this?</p>
  
  <pre><code>rails (3.2.13)
  cucumber-rails (1.3.1)
  cucumber (&gt;= 1.2.0)
