title: Installing/Running Thin Webserver on Rails 3
body: <p>Having an issue running the "Thin" web server. It looks like installation was successful but when I run "thin start" It appears as though Thin starts to initialize but then cannot find some resources it needs.</p>
  
  <p>Below, is the audit trail from my terminal session. Can someone offer a hand with this? According to the Thin docs, installation was done correctly. Thanks</p>
  
  <p><strong>Rails 3.2.12<br />
  ruby 1.9.3</strong></p>
