Check the cabal configure -v output. Check that you're picking up the
versions and locations of ghc and haddock that you expect.

Done. It now says:

cabal: Haddock's internal GHC version must match the configured GHC
version. The GHC version is 6.8.2 but haddock is using GHC version
6.10.1

That all looks sensible so my only suggestion is that it's not actually
using these ones. Check the configure output and compare the full paths
to the tools. If that provides now joy then in the worst case, use the
patch I applied to show what it thinks it is doing.
