Em Cygwin, como faço para instalar onda de hackage?

Question

A partir de um comando do Windows rápida,

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)

Eu instalei o pacote curl-devel do Cygwin, mas a partir de um prompt de cabal install curl Cygwin também falhar, mesmo se eu ponto --extra-lib-dirs e --extra-include-dirs para ele, por exemplo. ,

$ 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

As tentativas acima são com ghc-6.10.3, Cabal-1.6.0.3, e cabal-install-0.6.2.
