Не удалось установить mysql2 камень на RHEL 5.8 через Bundler

Question

Вот мой стек:

• RHEL 5.8 x86_64
• MySQL 5.5 x86_64
• Рубин 1.9.3p345
• Rails 3.2.8

Я устанавливаю mysql2 0.3.11 gem через bundler и получил ошибку, и проблема, похоже, не совпадает с популярными ошибками в Ruby gem mysql2 install failing a d mysql2 gem installation fails. Это пакеты, которые я уже установил для mysql.

[user@local config]$ yum list installed | grep MySQL 
Unable to read consumer identity 
MySQL-client.x86_64     5.5.29-1.rhel5     installed 
MySQL-devel.x86_64     5.5.29-1.rhel5     installed 
MySQL-python.x86_64     1.2.3-0.1.c1.el5     installed 
MySQL-server.x86_64     5.5.29-1.rhel5     installed 
perl-DBD-MySQL.x86_64     3.0007-2.el5      installed 
[user@local config]$ yum list installed | grep mysql 
Unable to read consumer identity 
libdbi-dbd-mysql.x86_64    0.8.1a-1.2.2      installed 

Сообщение об ошибке выглядит следующим образом:

An error occurred while installing mysql2 (0.3.11), and Bundler cannot continue. 
Make sure that `gem install mysql2 -v '0.3.11'` succeeds before bundling.

попробовать и использовать

bundle config build.mysql2 --with-mysql-config=/.../mysql_config 

или

sudo gem install mysql2 -- --with-mysql-config=/.../mysql_config
