Problemas al instalar la gema mysql2 en Mac OS Maverics

He adquirido una MacBook Pro con Mac OS Maverics y comencé a instalar mi ambiente de desarrollo para poder seguir actualizando mi sitio Quizzpot.com, primero instale MySQL utilizando el instalador oficial, luego instale RVM para descargar ruby-1.9.3 que es la versión que actualmente utilizo en Quizzpot.com, cuando intente descargar e instalar las gemas que utilizo me encontre con el siguiente problema.

$ bundle install
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

An error occurred while installing mysql2 (0.3.13), and Bundler cannot continue.
Make sure that `gem install mysql2 -v '0.3.13'` succeeds before bundling.

La solución fue desinstalar la versión que tenía de MySQL de la siguiente manera.

sudo rm /usr/local/mysql
sudo rm -rf /usr/local/mysql*
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/MySQL*
edit /etc/hostconfig and remove the line MYSQLCOM=-YES-
sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*
sudo rm -rf /var/db/receipts/com.mysql.*

E instalar MySQL utilizando Hombrew, que es un administrador de paquetes y dependencias para Mac OS, como no tenía instalado esta herramienta la instalé de la siguiente manera:

$ ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

Lo siguiente fue instalar MySQL:

$ brew install mysql

Y luego iniciar el servidor.

$ mysql.server start

Bastante sencillo realmente, y por último intentar nuevamente el bundle install. Esto resolvió el problema y las dependencias se instalaron correctamente!

Happy coding!
