I talked to Simon. We are puzzled. Maybe a file has moved, so that make
maintainer-clean isn't cleaning it. (That's something the build system is bad
about.)
Can you try in a completely fresh tree? And, if that fails, send (a url to)
the entire build log?

You can't define it *in* Haskell as user code. It is a built-in infix
type constructor (Either or Maybe are type constructors too, not just
types).
So it's a type constructor, not a type? Could you please provide a simple
example of its usage?
