嗨，我不确定我在做什么，基本上我试图通过自制软件将 ghc 和 haskell-platform 安装到我的 mac，但是由于我不明白的原因，ghc 不起作用，因此 haskell-platform 也不起作用
根据酿造医生：
Warning: Unbrewed .pc files were found in /usr/local/lib/pkgconfig.
If you didn't put them there on purpose they could cause problems when
building Homebrew formulae, and may need to be deleted.
Unexpected .pc files:
/usr/local/lib/pkgconfig/fuse.pc
its-fatbass:~ jellynom$ brew doctor

但根据某人的说法，这可以忽略？？？我似乎也找不到要删除它的文件（如果我应该删除它）

This brew is for GHC only; you might also be interested in haskell-platform.

configure: error: Your installation of ghc does not appear to work.
It cannot compile a simple program (see config.log for the details).
If you installed ghc from a generic binary tarball then it is worth
checking that you have the 'gmp' C library and header files installed.
(On Debian-based systems this package is called libgmp3-dev.)

我不知道如何检查 gmp c 库和头文件，他们推荐的链接也完全超出了我的想象；缺少有关 hscolor 的内容。
这是否意味着在安装 ghc 之前我应该安装其他东西？？？（除了 ghc 和 haskell-platform 之外，我没有通过 homebrew 安装其他任何东西）如果是这样，我应该安装什么？
