如何在 centos linux 上更新 pandoc？

我下载了 cabal-install-1.20.0.3.tar.gz 文件并解压，尝试运行时出现以下错误。我的目标是更新 pandoc。现在我有 pandoc 1.9，但我需要 1.12 版本。要更新 pandoc，我尝试更新 cabal 库。但没有成功

    No instance for (NFData Version)
      arising from a use of `rnf'
    Possible fix: add an instance declaration for (NFData Version)
    In the second argument of `seq', namely `rnf version'
    In the expression: rnf name `seq` rnf version
    In an equation for `rnf':
        rnf (PackageIdentifier name version) = rnf name `seq` rnf version

Error during cabal-install bootstrap:
Compiling the Setup script failed.

实际上我需要更新 cabal 但每次尝试都失败。

我尝试了 cabal install cabal-install 并收到以下错误

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.

附加说明：Centos 6.6
caball-install 版本 0.10.2 使用 Cabal 库
GHC 版本 7.0.4
haskell-platform-2011.4.0.0-6.el6.x86_64的版本 1.10.2.0
如何解决，请帮帮我！

经过长时间的谷歌搜索，我终于找到了解决方案。这个问题是由于 ghc 版本太旧造成的。我从以下网址下载了 ghc 7.8.3 源代码包：这里并安装它。

然后 ghc 7.8.3 有旧版本的 cabal，因此必须使用 从 ghc 7.8.3 中取消注册它 ghc unregister Cabal。

然后从 cabal-install-1.20 文件夹运行 bootstrap.sh 并成功获得 cabal-install 1.20 并运行， cabal update pandoc然后可以安装 pandoc 1.13 版本
