Cannot run "ruby script/server" rails/version (LoadError)

Question

I am facing a problem starting the server for a ruby app built by somebody else. When I run the "ruby server/script" command, the following output is generated:

ruby script/server 
./script/../config/../vendor/rails/railties/lib/initializer.rb:7:in `require': no such file to load -- rails/version (LoadError)
    from ./script/../config/../vendor/rails/railties/lib/initializer.rb:7
    from ./script/../config/boot.rb:45:in `require'
    from ./script/../config/boot.rb:45:in `load_initializer'
    from ./script/../config/boot.rb:38:in `run'
    from ./script/../config/boot.rb:11:in `boot!'
    from ./script/../config/boot.rb:109
    from script/server:2:in `require'
    from script/server:2

I have looked, and looked and no solution seems in sight.

Specs:

Ruby 1.8.7, 
Rails 2.2.2, 
gem -v 1.8.25

EDIT:
After doing that, I still get the same error:

[dralexmv@archbang rubygame]$ ruby script/server 
./script/../config/../vendor/rails/railties/lib/initializer.rb:7:in `require': no such file to load -- rails/version (LoadError)
    from ./script/../config/../vendor/rails/railties/lib/initializer.rb:7

Versions:

[dralexmv@archbang rubygame]$ gem -v 
1.4.2 
[dralexmv@archbang rubygame]$ rails -v 
Rails 2.2.2 
[dralexmv@archbang rubygame]$ ruby -v 
ruby 1.8.7 (2012-10-12 patchlevel 371) [x86_64-linux]

EDIT: GEM LIST

*** LOCAL GEMS ***

actionmailer (2.2.2)
actionpack (2.2.2) 
activerecord (2.2.2) 
activeresource (2.2.2) 
activesupport (2.2.2)

EDIT: Test on a test app

[dralexmv@archbang test_a]$ ruby script/server
=> Booting WEBrick...
=> Rails 2.2.2 application started on `http://0.0.0.0:3000`
=> Ctrl-C to shutdown server; call with --help for options

gem update --system 1.3.7 should fix the problem. Rails 2.x has some known issues running with gem -v 1.8.x — Anand Shah

Downgrade your gem and try. Rails 2.X doesn't work with gem version greater than 1.5

sudo gem update --system 1.4.2

could you post gem list ??

gems look good. Try creating new app.. rails test_app and try starting server for newly created app.

I downloaded this project to make some modifications on it on my local machine. I cannot seem to be able to start the server even when I have done no changes. This project is known to work. Gem list posted above

I think you have different version of rails app which you downloaded. Is there bundler in that app?? Is there Gemfile in that app??
