Как обновить Pandoc на Centos Linux?

Я скачал файл cabal-install-1.20.0.3.tar.gz и извлек его при попытке запустить, получаю следующие ошибки. Моя цель - обновить pandoc. Теперь у меня есть pandoc 1.9, но мне нужна версия 1.12. Чтобы обновить pandoc, я пытаюсь обновить библиотеку cabal. Но не повезло

На самом деле мне нужно обновить Cabal, но каждая попытка не удалась.

Я попытался установить Cabal Cabal-Install и получил следующие ошибки

cabal: cannot configure unix-2.7.0.1. It requires base >=4.5 && <4.8 For the dependency on base >=4.5 && <4.8 there are these packages: base-4.5.0.0, base-4.5.1.0, base-4.6.0.0, base-4.6.0.1, base-4.7.0.0 and base-4.7.0.1. However none of them are available. 

Дополнительное примечание: Centos 6.6
caball-install версии 0.10.2 с использованием версии 1.10.2.0 библиотеки Cabal
GHC версии 7.0.4
haskell-platform-2011.4.0.0-6.el6.x86_64
Как решить эту проблему, пожалуйста, помогите мне!
