title: Cannot redeclare composerRequire... - Composer issue?
body: <p>My development env is OS X Mavericks using MAMP and NetBeans.</p>
  
  <p>I'm experimenting with a CakePHP plugin (CakeResque) and after installing via Composer, the following error is being logged:</p>
  
  <blockquote>
    <p>Fatal error: Cannot redeclare composerRequiref2c9cc1d84da6e308a0f610da161cf55() (previously > declared in .../app/Vendor/composer/autoload_real.php:47) in
    .../app/Vendor/composer/autoload_real.php on line 50</p>
  </blockquote>
  
  <p>Others are using this plugin and at this point, I don't think it is related to the plugin.  The developer of the plugin has been kind enough to help me troubleshoot it through a <a href="https://github.com/kamisama/Cake-Resque/issues/70" rel="nofollow noreferrer">github issue</a> but with no luck.  In my core config file, I have:</p>
  
  <pre><code>require_once dirname(__DIR__) . '/Vendor/autoload.php';
  </code></pre>
  
  <p>I'm not requiring Vendor/autoload anywhere else in my application.</p>
  
  <p>I found this <a href="https://stackoverflow.com/questions/24234927/php-composer-cannot-redeclare">stackoverflow question</a> but it was never answered - this is the exact same issue I am having.</p>
  
  <p>Because I am using MAMP, I have pointed my local php to the MAMP php bin - now when I run <code>which php</code> it is pointing to my MAMP directory.  This may have nothing to do with it but I'm trying to include everything.</p>
  
  <p>Running <code>composer self-update</code> says everything is up to date.</p>
  
  <p>Any help is appreciated.</p>
