[Haskell-cafe] ghc-mtl, hint, mueval for ghc-7.6 ?

While porting some code to 7.6, I'm stuck here: Preprocessing library ghc-mtl-1.0.1.1... [1 of 1] Compiling Control.Monad.Ghc ( Control/Monad/Ghc.hs, dist/build/Control/Monad/Ghc.o ) Control/Monad/Ghc.hs:29:48: No instance for (DynFlags.HasDynFlags Ghc) this seems to block hint and mueval. Is there a known workaround for this problem, or a sugggested replacement package? Thanks - J.W.
