I update my GPU machine today by - Pulling BuildSystem, petsc-dev, thrust, cusp - Reconfiguring - Recompiling and none of the Thrust or Cusp things will build because VecType is again messed up. I look in the headers and the #undef VecType seems to be missing. Where did it go? and aren't we testing this?
