全新安装haskell-platform（通过homebrew）（GHC x64 7.6.3）OSX 10.9.2时，我在运行时收到以下警告ghc-pkg check（见下文）
Warning: haddock-interfaces: /Users/user/.cabal/share/doc/x86_64-osx-ghc-7.6.3/ghc-mod-3.1.7/html/ghc-mod.haddock doesn't exist or isn't a file

根据文档：
ghc-pkg check
Check the consistency of package depenencies and list broken packages.
Accepts the --simple-output flag.
我尝试运行以下命令来生成黑线鳕文档无济于事：
sudo cabal install --reinstall --force-reinstalls --enable-documentation
该命令来自用户在 haskell 邮件列表中的一个类似问题。 http://www.haskell.org/pipermail/glasgow-haskell-users/2012-February/021780.html
如何安抚ghc-pkg check和消除这些警告？
警告：当我说“全新安装”时，我的意思是我已经从头开始安装 Haskell 平台，并在全局范围内安装cabal-1.18.0.3并将 cabal 的 bin 目录添加到我的路径中。
