Hi Simon,

In InterfaceFile.hs in Haddock there is

binaryInterfaceVersion :: Word16
#if (__GLASGOW_HASKELL__ >= 711) && (__GLASGOW_HASKELL__ < 713)
binaryInterfaceVersion = 27
…

Try bumping this to 28 and if it works then then you may want to commit
the change.

By the way I see that there is a lot of output from Haddock now as I
made it print locations of missing documentation by default. Maybe
--no-print-missing-docs should be passed in for GHC stuff.
