title: Heroku - New Relic Agent not running error on rake db:migrate
body: <p>First time I've seen this error when running a migration on Heroku.</p>
  
  <pre><code>heroku rake db:migrate --app myapp
  (in /app)
  New Relic Agent not running.
  </code></pre>
  
  <p>I have the New Relic addon in my app addons so would this be an issue with the heroku platform or my app?</p>
  
  <p>edit: App is running on the bamboo-ree-1.8.7 stack.</p>
