[1 of 1] Compiling Network.OpenFlow ( Network/OpenFlow.hs, dist/build/Network/OpenFlow.o )

Network/OpenFlow.hs:906:25:
    Could not deduce (Num b) arising from the literal `0'
    from the context (Enum a, Bits b)
      bound by the type signature for
                 enumToBitInst :: (Enum a, Bits b) => [a] -> b
      at Network/OpenFlow.hs:905:18-45
    Possible fix:
      add (Num b) to the context of
        the type signature for
          enumToBitInst :: (Enum a, Bits b) => [a] -> b
    In the second argument of `f', namely `0'
    In the expression: f xs 0
    In an equation for `enumToBitInst':
        enumToBitInst xs
          = f xs 0
          where
              f xs' w = foldl (\ w x -> w `setBit` fromEnum x) w xs
