[4.8 OSX] Is the Leap plugin available?

I’m trying to run the example UE projects from the official Leap Demo Pack, but in the console I get many errors related to ‘/Script/LeapMotionController’ missing.
The Leap plugin appears to be enabled from the engine settings.

Am I doing something wrong?

Same issue in 4.8 P3

So, checking in the code it is still not available (not even 4.8). When can we expect to have this?
