Rails - Aug 2005 - replacing human_name

I''m trying to replace human_name following this howto: 
http://wiki.rubyonrails.com/rails/show/HowToAutomaticallyLoadFile

I''ve got this in environmant.rb:

require ''active_record_patch.rb''


#This is lib\active_record_patch.rb
class ActiveRecord::Base::Column
   alias __human_name human_name

   #make new version optionally take a language parameter.
   def human_name(lang = nil)
     return ''OK''+__human_name
   end
end
#####

This is the error: it complains for not being able to find human_name.

R:\>ruby script\server
./script/../config/../lib/active_record_patch.rb:2: undefined method 
`human_name'' for class `ActiveRecord::Base::Column''
(NameError)
         from 
c:/programmi/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:18:in 
`require__''
         from 
c:/programmi/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:18:in 
`require''
         from 
c:/programmi/ruby/lib/ruby/gems/1.8/gems/activesupport-1.1.1/lib/active_support/dependencies.rb:200:in
`require''
         from ./script/../config/environment.rb:87
         from 
c:/programmi/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:18:in 
`require__''
         from 
c:/programmi/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:18:in 
`require''
         from script/server:42

Any idea  about what happens?

thanks

ActiveRecord::ConnectionAdapters::Column is what you want here.
