GEM Version Requirements Deprecated

Question

When creating a new Rails project with:

rails sample

Then create a model using:

script/generate model person first_name:string last_name:string

Everything is fine. However, if I add any gems to my environment. Rb:

config.gem "authlogic"

And run the same generator, I get the following:

/Library/Ruby/Gems/1.8/gems/rails-2.3.5/lib/rails/gem_dependency.rb:119:Warning: Gem :: Dependency on # version_requirements has been deprecated and will be removed after August 2010.

A warning has recently appeared (I think), but I would like to fix it, if possible. Any hints or similar experiences?

Thank.

Entering these lines in your config / environment.rb between your bootstrap and your initializer will remove the failure warning:

if Gem::VERSION >= "1.3.6"
  module Rails
    class GemDependency
      def requirement
        super == Gem::Requirement.default ? nil : super
      end
    end
  end
end
