如何解决向量算法包、darcs和其他软件的cabal-install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 

下面是错误：

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和time-1.2.0.3包，这些包已经存在于全局包数据库中。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:

我试着用ghc-pkg注销所有的dup，但都没有用。我也尝试过ghc-pkg check，它不会返回任何东西，永远不会。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，这就是我目前所在的位置。这是删除所有内容并重新安装cabal-install后的结果：

这些不是阴谋论的错误。向量包还没有在GHC7中构建出来。你是一个早期采用者，在Haskell平台版本发布之前就跳上了GHC7。

作为早期采用者，您的职责是向包维护者报告构建错误。
