我不明白该错误，因为它似乎需要我尝试安装的同一软件包的版本。

$ cabal install gtk-mac-integration

它不想要 Haskell 包gtk-mac-integration，它想要系统包gtk-mac-integration。也就是说，您尝试安装的 Haskell 包只是对gtk-mac-integration库的绑定（我认为它与 GTK+ 捆绑在一起）；在安装 Haskell 包之前，您必须单独安装它。

如果您已经安装了 GTK+，那么问题是pkg-configCabal 用来查找外部库依赖项的工具无法找到该.pc库的相应文件。不过，我不知道如何解决这个问题；至少不是没有更多细节。
