rails 3.1RC4でmysqlを使用

Question

mysqlで動作するようにレール3.1RC4を取得できません...？

私はちょうど新しいテストアプリを作りましたが、そこにも失敗しますか？

私がやった：私のgemfileに、新しいblog2の-d mysqlの

レール：宝石 'mysql2'

をdatabase.ymlのファイルに：

development: 
    adapter: mysql2 
    encoding: utf8 
    reconnect: false 
    database: blog2_development 
    pool: 5 
    username: root 
    password: password 
    socket: /tmp/mysql.sock 

今私はレールのを実行すると

と私はこのバージョンを参照のmysql --versionを入力する際に​​mysqlのオフ32ビット版をインストール：

バンドルインストールmysql Ver 14.14 Distrib 5.5.15, for osx10.6 (i386) using readline 5.1

をし、サーバが起動します。.. 。

何か提案がありますか？ に関して、 タイス
