title: installing Webistrano RAILS_ENV=production rake db:migrate fails on Mac OS 10.6.8
body: <p>I've been trying to install Webistrano. I have installed all the dependencies required for it, including Capistrano, as described on the github wiki: <a href="https://github.com/peritor/webistrano/wiki/Installation" rel="nofollow">https://github.com/peritor/webistrano/wiki/Installation</a>. I have googled these error messages and have not found any helpful info.</p>
  
  <p>When running RAILS_ENV=production rake db:migrate I get the following error messages:</p>
  
  <p>SUDO</p>
  
  <pre><code>webistrano username$ sudo RAILS_ENV=production rake db:migrate
