Ah yes, I get this too when using ghc 6.6.
With ghc 6.4.2 the haddock goes through fine.

Updating haddock to 0.8 and the ghc-pkg error is still there.
But the docs seem to be generated ok:
    Main
    Synopsis
    main :: IO ()
    Documentation
    main :: IO ()
    main runs the main program
    Produced by Haddock version 0.8

Simon, know what's going on?
