所以我得到的错误是：

Could not find module `Text.XML.HXT.Curl':
    Use -v to see a list of the files searched for.

我试过了 ：

:! cabal install curl

但我得到一个错误,它必须在unix或cygwin上,所以我继续安装cygwin,现在它说：

checking for gcc... gcc
checking for C compiler default output file name... configure: error: C compiler cannot create executables
See `config.log' for more details.
cabal: Error: some packages Failed to install:
curl-1.3.7 Failed during the configure step. The exception was:
ExitFailure 77

:! gcc -version
Access is denied

我尝试下载curl包并使用cmd：runHaskell Setup.hs configure进行安装,但是我得到了这个：

Setup.hs: Missing dependency on a foreign library:
Missing C library: curl
This problem can usually be solved by installing the system package that provides this library (you may need the "-dev" version)

尝试在cygwin中安装gcc,g,libcurl,make仍然失败.

尝试安装mingw / mysis,我也失败了.关于curl / curl.h缺失的东西.

有没有人成功,可以告诉我他是怎么做到的？
