title: ZenTest not working with RSpec 2.7 and Rails 3.1.0
body: <p>I've basically followed <a href="https://www.relishapp.com/rspec/rspec-rails/docs/autotest" rel="nofollow">this RSpec guide</a> on my simple Rails app, but when I run autotest I get</p>
  
  <pre><code>$ autotest
  (Not running features.  To run features in autotest, set AUTOFEATURE=true.)
  loading autotest/rails_rspec2
  bundle exec /Users/darth/.rvm/rubies/ruby-1.9.2-p290/bin/ruby -S /Users/darth/.rvm/gems/ruby-1.9.2-p290/gems/rspec-core-2.7.0/bin/rspec --tty '/Users/darth/projects/checkin/spec/models/player_spec.rb'
  /Users/darth/.rvm/rubies/ruby-1.9.2-p290/bin/ruby: No such file or directory -- /Users/darth/.rvm/gems/ruby-1.9.2-p290/gems/rspec-core-2.7.0/bin/rspec (LoadError)
  </code></pre>
  
  <p>When I look at the gem directory, it looks like there's <code>exe</code> folder instead of <code>bin</code></p>
  
  <pre><code>$ ls ~/.rvm/gems/ruby-1.9.2-p290/gems/rspec-core-2.7.0/
  README.md exe       features  lib       spec
  
  $ ls ~/.rvm/gems/ruby-1.9.2-p290/gems/rspec-core-2.7.0/exe/
  autospec rspec
  </code></pre>
  
  <p>And this is my Gemfile</p>
  
  <pre><code>group :test, :development do
    gem 'rspec-rails'
  end
  
  group :test do
    # Pretty printed test output
    gem 'turn', :require =&gt; false
    gem 'rspec'
    gem 'cucumber-rails'  
    gem 'database_cleaner'
    gem 'webrat'
    gem 'capybara'
    gem 'ZenTest', '~&gt; 4.4.2'
    gem 'autotest-rails', '~&gt; 4.1.0'
  end
  </code></pre>
