Not sure what is in the platform as I just did the following:

cabal install -j3 haddock

If nobody else is seeing the problem I did, I don't think we should worry about it.

For reference, here is the link for the ghc 7.10.2 Haddock ticket I mentioned, "Update Haddock for 7.10.2"

When you did the cabal install of haddock, which haddock did you get? Isn't 2.16.0 the latest? And that should be what is in the Platform.

I guess I should check that the haddock in GHC is actually 2.16.0!
