Ruby On Rails - HTTP 500

Hopefully someone can help me with this.

I created a new RoR app through the control panel. Then followed the instructions to install the sqlLite ruby gem from source I then followed the "Deploying a Ruby on Rails Application" guide to deploy my own app.

After deploying my own app I ran bundle install and it ran without error.

It is a very basic RoR app it has one controller called static_pages and two views called home and about to go with it.

the routes.rb has this:

get "static_pages/home"  
get "static_pages/about"

Now when I got to my site: http://username.webfactional.com/static_pages/home and I get an Internal Server Error (500)

Here is what is in the nginx error.log

cache: [GET /assets/rails.png] miss
cache: [GET /static_pages/home] miss
cache: [GET /static_pages/home/] miss
cache: [GET /assets/rails.png] miss

2012/03/16 21:17:01 [emerg] 19415#0: still could not bind()
cache: [GET /static_pages/home] miss
cache: [GET /static_pages/home] miss

Since I'm still very new to RoR, I have no idea what is causing the problem especially since this very basic.

Any help would be greatly appreciated
