Rails 2.3.x compatibility broken

[knightq]

Since your gem requires "ActiveSupport::Concern" (module controller_mixin extends from that) that is present only from Rails 3.0...

How can I use your gem on Rails 2.3.x?

Hi - we've got breadcrumbs_on_rails working on a Rails 2.3.10 app - you need v1.x of the gem though. Put the following in your Gemfile:

gem "breadcrumbs_on_rails", "~>1.0"

BreadcrumbsOnRails 2.x requires Rails 3. Use BreadcrumbsOnRails 1.x with Rails 2.
