Не удается установить модуль CPAN Perl на RHEL 7 (Amazon EC2)

Я пытаюсь установить x2goserver на свой сервер RHEL 7. У меня возникли проблемы с зависимостями, точно такие же, как здесь вопрос (я не знаком с Perl или CPAN, я просто хочу работающий x2goserver), поэтому, когда я попытался установить модули CPAN Perl, как описано в ответе, на этот раз я столкнулся со следующим выводом :
