[Haskell] Missing docs on Debian?

Using Debian testing with the ghc6-doc package installed (version 6.4-3), I just noticed that I only seem to have the "Hierarchical Libraries" manual, but not the "User's Guide" nor the "Cabal" docs (nor hslibs docs). Those links are broken on the "index.html" page that was installed. Did I do something wrong, or is there a reason that those were omitted? Thanks, Yitz
