Here is my stack:
- RHEL 5.8 x86_64
- MySQL 5.5 x86_64
- Ruby 1.9.3p345
- Rails 3.2.8
I am installing mysql2 0.3.11 gem through bundler and got the error, and the problem seems not to be the same with the popular errors at Ruby gem mysql2 install failing and mysql2 gem installation fails. These are the packages I've already installed for mysql.
[user@local config]$ yum list installed | grep MySQL
