On Cygwin, how do I install curl from hackage?

From a Windows command prompt,

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)

I have installed Cygwin's curl-devel package, but from a Cygwin prompt cabal install curl also fails, even if I point --extra-lib-dirs and --extra-include-dirs at it, 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

The above attempts are with ghc-6.10.3, Cabal-1.6.0.3, and cabal-install-0.6.2.

Just use cygwin's setup.exe to install packages - or use cyg-apt (code.google.com/p/cyg-apt) to do it. - Lastly if the package isn't in cygwin's package list, get the source and configure/make. – ocodo
