[ 8 of 11] Compiling Import           ( Import.hs, dist/build/darcs-fastconvert/darcs-fastconvert-tmp/Import.o )

Import.hs:333:29:
    Couldn't match expected type `IO
                                    (Darcs.Patch.Witnesses.Sealed.FreeLeft p0)'
                with actual type `Tree m0 -> m0 (w0 (FL prim0))'
    In the return type of a call of `treeDiff'
    Probable cause: `treeDiff' is applied to too few arguments
    In the first argument of `liftIO', namely
      `(treeDiff (const TextFile) start current)'
    In the second argument of `(<$>)', namely
      `liftIO (treeDiff (const TextFile) start current)'

    NB: `PrimOf' is a type function, and may not be injective
    Expected type: RL (PrimOf p) cX cY
      Actual type: RL (PrimOf t0) cX cY
    In the second argument of `(:<:)', namely `newPs'
    In the expression: move uFrom uTo :<: newPs
