No Views integration showing up

I am using Views 6.x-2.2 and VotingAPI 6.x-2.0-rc2. I have created a bunch of content types, some with voting data courtesy of the VotingAPI and Plus1 modules in tandem, and I have just gone to create a view sorting results by votes, but there are no VotingAPI options under Filters or Sort Criteria in the Views UI? What gives? I'm sure I've seen them before, but memory is fuzzy and it was D5/Views 1.x ...

I guess I'm missing something? Or is the Plus1 module supposed to provide the Views stuff?
