Ambiguous occurrence of InstalledPackageInfo_

I'm running into some compile errors while trying prepare the haskell-docs package for Debian.

Preprocessing library haskell-docs-4.2.2...

I tried a few quick hacks with no luck. It could be our version of cabal. I'd be happy to patch this but a hint would really help.

Hmm, haskell-docs should build with the versions specified in the GHC file. Please state your versions of ghc and cabal.

ghc - 7.6.3 cabal-install - 1.20.0.3 Cabal - 1.20.0.2

Is this still an issue?
