rake aborted while using gem 'mysql2', '< 0.3'

Question

Hi am having this in my gemfile

gem 'rails', '3.0.5'

gem 'mysql2', '< 0.3'

and in my database.yml I have written this code

development:
  adapter: mysql2
  encoding: utf8
  pool: 5
  database: railsquiz
  timeout: 5000
  username: root
  password: test
  socket: /var/run/mysqld/mysqld.sock

Now I had run bundle install and got this version of mysql2-0.2.24. When am doing

rake db:create

its giving me error

rake aborted!
