Installing mysql2 gem for Ruby on Rails 3.1.0

Question

I get this error

Gem files will remain installed in
/home/mark/.bundler/tmp/28288/gems/mysql2-0.2.17 for inspection.
Results logged to
/home/mark/.bundler/tmp/28288/gems/mysql2-0.2.17/ext/mysql2/gem_make.out
An error occured while installing mysql2 (0.2.17), and Bundler cannot
continue. Make sure that gem install mysql2 -v '0.2.17' succeeds
before bundling.

With a Ruby on Rails application and I can not solve it.
