OK. I'll file a placeholder bug report so this doesn't get forgotten.
I understand the reason for leaving it as is for now, but hope that we
avoid creeping dependence on more tools.

BTW, now that ghc distributes its own version of haddock, could that
version be renamed to avoid the obvious namespace clash?  Macports
will rename ghc's haddock to haddock-ghc so it doesn't conflict with
the one installed from hackage.  Or is there a better plan?

Best Wishes,
