Установите гем mysql2 на Snow Leopard для Rails 3 с помощью rvm

Недавно я обновился до Rails 3 и создал новое приложение с Rails 3.0.3, но все время получаю сообщение об ошибке

Macintosh:$ rails server

RuntimeError (!!! Missing the mysql2 gem. Add it to your Gemfile: gem 'mysql2'):

У меня 64-битная машина. Ошибки есть только в документации, и похоже, что гем был установлен правильно.

Macintosh:$ env ARCHFLAGS="-arch i386" gem install mysql2 -- --with-mysql-config=/usr/local/mysql/bin/mysql_config

Я добавил гем в свой GemFile

source 'http://rubygems.org'

gem 'rails', '3.0.3'
gem 'mysql2'
gem 'sqlite3-ruby', :require => 'sqlite3'

Мой GemFile.lock выглядит так

mysql> 

Это все, что у меня есть в моем новом приложении, но у меня все еще возникает проблема с отсутствующим гемом mysql2.

У меня Snow Leopard 10.6.5 с установленным X Code 3.2.4.

Есть идеи?

Заранее благодарим!
