如何解决矢量算法包、darcs 等的 cabal 安装错误？

Question

$ ghc -V; cabal -V
The Glorious Glasgow Haskell Compilation System, version 7.0.1
cabal-install version 0.8.2
using version 1.8.0.6 of the Cabal library 

这是错误：

$ cabal install vector-algorithms

我还注意到，当我安装 cabal-install 时，它安装了 process-1.0.1.4、random-1.0.0.3、Cabal-1.8.0.6、 以及已经存在于全局包数据库中的 time-1.2.0.3 包。 例如，尝试安装 darcs 和其他软件包时，我收到以下信息：

Resolving dependencies...
<command line>: cannot satisfy -package Cabal-1.10.0.0: 
    Cabal-1.10.0.0-30b3f082077a2793c432ea426276c8f9 is unusable due to missing or recursive dependencies:

    (use -v for more information)
cabal: Error: some packages failed to install:

我尝试使用 ghc-pkg 注销所有重复项，但这没有帮助。 我还尝试了 ghc-pkg 检查，但它不会返回任何内容。 我尝试重新开始，删除所有本地数据库，包括 $HOME/.cabal/，然后重新安装 cabal-install，这就是我目前所处的位置。 这是删除所有内容并重新安装 cabal-install 后的结果：

这些不是阴谋集团的错误。矢量包尚未与 GHC 7 一起构建。您是早期采用者，在 Haskell 平台版本发布之前就开始使用 GHC 7。

作为早期采用者，您的职责是向软件包维护人员报告构建错误。
