This is a bug in the haddock.cabal file. Haddock 2.1 doesn't support GHC 6.8.3. The next release will, and it will come out soon. David 2008/7/30 Jason Dusek :

I am unable to build Haddock 2.1, with the odd error:

src/Haddock/GHC/Typecheck.hs:82:4: Constructor `HsModule' should have 7 arguments, but has been given 8

What is the root of it, you think?
