Problems with "wrong number of arguments (2 for 1) (ArgumentError)"

I'm trying initialize my local rails server but I haven't been able to, because when I write "rails server", show me this message:

=> Booting WEBrick 
=> Rails 3.0.3 application starting in development on http://0.0.0.0:3000 
=> Call with -d to detach 
=> Ctrl-C to shutdown server

That appears to be a bug in "/home/distriker/Documentos/public_html/auth/mysql2/ruby/1.8/gems/ activesupport-3.0.3/lib/active_support/dependencies.rb" line 239. It's calling:

require 'one/thing', 'another/thing'

It's possible that something in your config is causing it to do this.

[Off-topic] English help :)

1. "I haven't can" => "I haven't been able to"
2. "Rewards, Iván" => "Regards, Iván"

Hopefully you don't mind. [/Off-topic]

EDIT | I'd probably check this line first: "/home/distriker/Documentos/public_html/auth/config.ru:6"
