[Rails] Why am I getting "undefined local variable or method `acts_as_taggable'"?

[softwareengineer 99]

Ok guys it was really silly. I got it figured out.
  
  Just remember whenever you modify your environment.rb file, remember to restart the web server.
  
  Long day for me.

  I recently installed  acts_as_taggable using the following command:
  
gem install acts_as_taggable
# output follows
Attempting local installation of 'acts_as_taggable'
Local gem file not found: acts_as_taggable*.gem
Attempting remote installation of 'acts_as_taggable'
Updating Gem source index for: http://gems.rubyforge.org
Successfully installed acts_as_taggable-1.0.4
Installing RDoc documentation for acts_as_taggable-1.0.4...
  And added the following line to environment.rb
  require_gem "acts_as_taggable-1.0.4"
  
  However when I add the following to my target class (resource.rb):
  acts_as_taggable
  
  I get the following error 
  
undefined local variable or method `acts_as_taggable' for Resource:Class

Why am I getting this error and how can I fix it? My installation seemed to have gone OK so what am I missing here?

I have been searching everywhere and a

 pointers are greatly appreciated.

Thanks
Frank
