Error with Phusion Passenger while setting up Rails on Ubuntu Server - ruby-on-rails

Question

I need help getting a rails app running on an Ubuntu 11.10 Server.
I have been at it for about 2 days and can't get past the part shown in the screen shot here. I have rvm, rails, ruby, capistrano, fusion passenger all installed correctly as far as I can tell. I think the issue I have has to do with the database (mysql) or getting rails to talk to the database (I'm just making a guess from the error messages below).
Error message:
undefined method `active_record' for #<Rails::Application::Configuration:0x00000002e43fe8>
Exception class:
NoMethodError
Application root:
/var/www/jamesbay/blog/current
My main question is how can I go about debugging this?
I have tried modifying the config.ru file, application.rb, and environment.rb as listed with no resolution. I'm not entirely sure what these errors even imply!
I have capistrano deploying to my directory on the server properly.
I can make updates to a git repo and use the various 'cap' commands to handle the actual deployment from local machine to server.
Any help is appreciated! (I have only been using rails for about 2 weeks and I have already learned a TON about server management due to this project)

Answer 1

I ended up resolving my issue.
The primary issue was due to having multiple versions of ruby installed and managed with rvm.
This coupled with not properly initializing my database AND not setting up my apache paths properly led to the errors.
My default ruby version was set to ruby-1.9.3-p286 but I was using ruby-1.9.3-p194 on my development machine. I had previously installed both versions on the server but didn't pick a default. Make sure you pick a default version before deployment.
I am using sub URI's and I hadn't set up the paths properly with symlinks. For example, I have my application files inside /home/username/appName, with the public directory living at /home/username/appName/current/public. Inside my DocumentRoot, /var/www I created a symlink called 'appName' that points to the public directory path. Where I messed up was in not defining the RackBasedURI path in my /etc/apache2/sites-available/default file.
