ROR + Невозможно установить tiny_tds

Здесь я пытаюсь получить данные из MS-SQL Server 2008 в свое приложение Rails на Ubuntu 10. Но я не могу установить tiny_tds . Я следую шагу, указанному на github. Но ответа нет. Пожалуйста, помогите мне правильно настроить.

Используется команда gem :: gem install tiny_tds

Также эта команда :: gem install tiny_tds –with-freetds-include = / usr / local / include / freetds –with-freetds-lib = / usr / local / lib

Ошибка:
