在Cygwin，如何从hackage安装卷曲？

Question

从Windows命令提示，

c:\>cabal install curl
Resolving dependencies...
Configuring curl-1.3.5...
cabal: Error: some packages failed to install:
curl-1.3.5 failed during the configure step. The exception was:
sh: runGenProcess: does not exist (No such file or directory)

我已经安装Cygwin的卷曲devel包，而是从一个Cygwin的提示cabal install curl也失败，即使我点--extra-lib-dirs和--extra-include-dirs它， e.g。，

$ cabal install curl --extra-include-dirs=c:/cygwin/usr/include \
                     --extra-lib-dirs=c:/cygwin/usr/lib
Resolving dependencies...
Configuring curl-1.3.5...
[...]
configure: error: curl libraries not found, so curl package cannot be built
See `config.log' for more details.
cabal.exe: Error: some packages failed to install:
curl-1.3.5 failed during the configure step. The exception was:
exit: ExitFailure 1

上述尝试与GHC-6.10.3，卡瓦尔-1.6.0.3，和小集团安装-0.6.2。
