Type `OVRDisplay' does not contain a definition of setviewport

Hello All,
I am a newbie to Unity-Oculus Integration. I have Unity 5.2.1p3 and it is already showing me an error :

Assets/OVR/Editor/OVRGameView.cs(48,52): error CS1061: Type OVRDisplay' does not contain a definition for SetViewport’ and no extension method SetViewport' of type OVRDisplay’ could be found (are you missing a using directive or an assembly reference?)

I am not able to get rid of it, as I am not able to find the solution anywhere in the posts(Oculus Forums as well).
I have installed Oculus 0.7 Runtime and SDK.

I need your help guys.

did you figure this out? i get the same error

I’m running into this same issue this morning. 5.3.2f1 Personal, Oculus Utilities, Mobile SDK 1.0.0.

Where any of you able to get it to run?
