Error when starting rails, what does it mean?

Hi,

Can anyone tell me what the below error means when I'm trying to start rails? I'm using Fedora LInux Core 5. After visiting the rails setup page (http://www.rubyonrails.org/down), I'm getting stuck in the "Make your application" section. Specifically, when I type in "ruby script/ server" I get the below error. What does it mean and how can I resolve it?

[root@remandev refillingstation]# cd /usr/local/apache2/htdocs/ testrails [root@remandev testrails]# ruby script/server => Booting Mongrel (use 'script/server webrick' to force WEBrick) => Rails application starting on http://0.0.0.0:3000 => Call with -d to detach => Ctrl-C to shutdown server Exiting /usr/local/lib/ruby/gems/1.8/gems/rails-1.2.5/lib/commands/servers/ mongrel.rb:15: warning: already initialized constant OPTIONS /usr/local/lib/ruby/gems/1.8/gems/rails-1.2.5/lib/commands/servers/ mongrel.rb:18: undefined method `options' for #<Array:0xb7b3b110> (NoMethodError)         from /usr/local/lib/ruby/site_ruby/1.8/rubygems/ custom_require.rb:32:in `gem_original_require'         from /usr/local/lib/ruby/site_ruby/1.8/rubygems/ custom_require.rb:32:in `require'         from /usr/local/lib/ruby/gems/1.8/gems/activesupport-1.4.4/lib/ active_support/dependencies.rb:495:in `require'         from /usr/local/lib/ruby/gems/1.8/gems/activesupport-1.4.4/lib/ active_support/dependencies.rb:342:in `new_constants_in'         from /usr/local/lib/ruby/gems/1.8/gems/activesupport-1.4.4/lib/ active_support/dependencies.rb:495:in `require'         from /usr/local/lib/ruby/gems/1.8/gems/rails-1.2.5/lib/ commands/server.rb:39         from /usr/local/lib/ruby/site_ruby/1.8/rubygems/ custom_require.rb:27:in `gem_original_require'         from /usr/local/lib/ruby/site_ruby/1.8/rubygems/ custom_require.rb:27:in `require'         from script/server:3
