rails does not recognize mysql2 gem

I'm unable to have rails recognize the mysql2 gem that I've installed. I'm using rails 3.1 and ruby 1.9.2. I'm stumped here..

Rails will automatically use Bundler.setup when starting, it is equivalent with bundle exec from command line, to allow loading mysql gem you need it to your Gemfile and run bundle install, best if you place it in proper group - some projects use pg for production and mysql for development, if you plan always using it then it can be specified without group.
