問題在Mac OS上安裝哈斯克爾圖書館的regex，PCRE X

我試圖使用安裝哈斯克爾regex-pcre庫：問題在Mac OS上安裝哈斯克爾圖書館的regex，PCRE X

cabal install --extra-include-dirs=/usr/local/include \ 
       --extra-include-dirs=/usr/include regex-pcre

但是我得到這個奇怪的錯誤：

的要點這，似乎是無法找到第二個float.h文件：

/usr/include/float.h:8:24: error: float.h: No such file or directory

我已經Ø pened /usr/include/float.h和8號線讀取：

#include_next <float.h>

我已經做了我在谷歌搜索，雖然我不知道多少CI想我明白那是什麼線應該說但是......我不知道如何真正解決這個問題。我不知道我的系統上還有一個float.h文件。

我正在使用的GHC和GCC版本。 GCC來自XCode 4.GHC是32位，但我也嘗試過64位版本，結果相同。

$ gcc --version 
i686-apple-darwin10-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5666) (dot 3) 

$ ghc --version 
The Glorious Glasgow Haskell Compilation System, version 7.0.2

OS X版本是10.6.7。

任何幫助非常感謝。
