#rails hoge

#rake db:create

!!! The bundled mysql.rb driver has been removed from Rails 2.2. Please install the mysql gem and try again: gem install mysql.
rake aborted!
no such file to load -- mysql

ubuntu10.04なんですが↑のエラーがでます

#sudo gem install mysql -- --with-mysql-config=/usr/bin/mysql_config

をやっても同じエラーが出ます
どなたか教えてください・・・
