I'm trying to run a simple cocos2djs project but when I try to test on the simulator the build fails with this error:

I'm using the latest iOS SDK version (9.2) running in the MacOS 10.11.
I've already prebuilt the libraries, see below the result of rapidgame show command.
Rapidgame lives here: /Users/gzomer/.rapidgame
Latest static libs and headers: /Users/gzomer/.rapidgame/3.9
Static libs and headers have been built: YES
Have I missed any step?
