xmonad built fine with GHC HEAD but XMonadContrib failed with the following build error: XMonad/Layout/MultiToggle.hs:162:9: Could not deduce (HList b w0) arising from the ambiguity check for `??' from the context (HList b w) bound by the type signature for ?? :: HList b w => a -> b -> HCons a b at XMonad/Layout/MultiToggle.hs:162:9-42 The type variable `w0' is ambiguous In the ambiguity check for: forall a b w. HList b w => a -> b -> HCons a b In the type signature for `??': ?? :: HList b w => a -> b -> HCons a b Can anyone suggest a fix?
