how to install haskell openid package in windows - windows

Question

haskell 'openid' package depends on HsOpenSSL and nano-hmac packages which requires openssl. I've compiled openssl for MinGW in C:\OpenSSL\ directory and installed openid package with following command:
cabal install openid --extra-include-dirs=C:\OpenSSL\outinc --extra-lib-dirs=C:\OpenSSL\out
When I'm trying to compile haskell program using this package I'm receiving lots linking errors.
test.hs:
import Network.OpenID
main = print "ok"
ghc --make test.hs:
Linking test.exe ...

What I'm doing wrong?

I suspect there may be a version mismatch somewhere. Try using the precompiled binaries for OpenSSL here: http://www.openssl.org/related/binaries.html
I was able to get the instructions here to work with the latest version of HsOpenSSL: http://hackage.haskell.org/trac/ghc/wiki/Builder (in fact I worked with the maintainer to make these instructions work without needing to patch the package.)
