How to install haskell openid package on windows

Question

The haskell 'openid' package depends on the HsOpenSSL and nano-hmac packages that require openssl. I compiled openssl for MinGW in the C: \ OpenSSL \ directory and installed the openid package with the following command:

cabal install openid --extra-include-dirs=C:\OpenSSL\outinc --extra-lib-dirs=C:\OpenSSL\out

When I try to compile a haskell program using this package, I get a lot of error references.

test.hs:

import Network.OpenID

main = print "ok"

ghc --make test.hs:

Linking test.exe ...

What am I doing wrong?

I suspect there might be a version mismatch. Try using the precompiled binaries for OpenSSL here: http://www.openssl.org/related/binaries.html
