    MySQL is required to install.

    You can install this with Homebrew using:
      brew install mysql-connector-c
        For MySQL client libraries only.

      brew install mysql
        For MySQL server.

    Or you can use an official installer from:
      http://dev.mysql.com/downloads/mysql/
    EOS
  end

  def satisfied?
    which 'mysql_config'
  end
