gem install mysql2 でエラーが発生し、どうしてもインストールできない。エラーはどうやらインストールされている mysql のヘッダ等が読み込めないとのことなので、gem install オプションを付けた。
しかし、どうしてもうまくいかない。
$ gem install mysql2 -- --with-mysql-dir=/usr/local/mysql --with-mysql-lib=/usr/local/mysql/lib/ --with-mysqlclientlib=/usr/local/mysql/lib --with-mysql-include=/usr/local/mysql/include/

mysql 32bit版から、64bit版へ再インストール。
gem install mysql2 が動きました。

でも、32bit版PCで、64bit版のmysqlが動くのかいな？という感じです。狐につままれた感じ。
