No, no, Repa is build against 0.9.1 since vector-0.9.1 appears in the
_expected_ type, that is the type expected by the environment of the
expression, here that's fromUnboxed which comes from the Repa library,
so if it's waiting for a Vector from vector-0.9.1 it means Repa is
built against this version (which is not the latest on your computer
thus the problem).
