Loaderror for mysql2 while starting ruby on rails app

I am trying to start the ruby on rails application that i had to my old mac which i transferred all data to the new one (el capitan).

I tried to bundle install, bundle update everything, the database.yml looks fine,but the application doesn't begin due to the following error.

I have two versions of mysql2, but if i delete the 0.4.2 and i try to bundle install (it installs 0.4.2) and if rails s (it requires the 0.4.2)

Any idea??

/Users/glouk/.rvm/gems/ruby-1.9.3-p448@global/gems/bundler-1.11.2/lib/bundler/rubygems_integration.rb:314:in `block in replace_gem': Please install the mysql2 adapter: `gem install activerecord-mysql2-adapter` (can't activate mysql2 (~> 0.3.10), already activated mysql2-0.4.2. Make sure all dependencies are added to Gemfile.) (LoadError)
