GHC cabal install hamlet завершается неудачно с неясной ошибкой

Я пытаюсь установить Hamlet на общий сервер веб-фракции, чтобы я мог скомпилировать и запустить там свое веб-приложение. Я использую Yesod для разработки приложения.

Мне удалось скомпилировать GHC 7 из исходников и установить самонаводящуюся cabal. Затем я выполнил cabal install hamlet и ожидал, что это сработает. Не повезло!

Я получаю следующее странное сообщение об ошибке от Cabal / GHC. Может ли кто-нибудь мне помочь?
