Hi Haskell Cafe,

I have some code that compiles when running on GHC on OS X, but not on Ubuntu:

    No instance for (hashable-1.2.1.0:Data.Hashable.Class.GHashable
                       (GHC.Generics.Rep Point))
      arising from a use of `hashable-1.2.1.0:Data.Hashable.Class.$gdmhashWithSalt'
    Possible fix:
      add an instance declaration for
      (hashable-1.2.1.0:Data.Hashable.Class.GHashable
         (GHC.Generics.Rep Point))
    In the expression:
      (hashable-1.2.1.0:Data.Hashable.Class.$gdmhashWithSalt)
    In an equation for `hashWithSalt':
        hashWithSalt
          = (hashable-1.2.1.0:Data.Hashable.Class.$gdmhashWithSalt)
    In the instance declaration for `Hashable Point'

Anyone know what's happening here?

Cheers,
