For Rails 3, vary the instructions given in the article from @science's answer. In your environments/development.rb file, add the lines:

ActiveSupport::Dependencies.autoload_paths << File::join( Rails.root, 'lib')
ActiveSupport::Dependencies.explicitly_unloadable_constants << 'MyModuleInLibFolder'

Of course, substitute the name of your module for MyModuleInLibFolder.
