[Haskell-cafe] Haddock on HP failing

Hi, I am trying to use Haddock on the Haskell Platform 2010.1.0.0 and getting haddock.exe: can't find a package database at E:\ghc\ghc-6.12.1\lib\package.conf.d I have tried uninstalling and re-installing HP (just in case) to no avail. Has anybody else seen this? Chris
