OSX 10.8, GT650M, OpenCL Hello World example fails; Can't create command queue

The official `Open Cl Hello World` example http://developer.apple.com/library/mac/#samplecode/OpenCL_Hello_World_Example/In troduction/Intro.html

fails with "Can't create command queue" err: -30, CL_INVALID_VALUE, as does the examples from the OpenCL books http://code.google.com/p/opencl-book-samples/ .

 

I'm on a fresh install of XCode 4.4.1, OS X 10.8.1 and don't know how to proced. I crossposted this issue to the MacRumors Forum, where other users stated that the code works. I'm beginning to think that I have a faulty machine/driver/installation but want to do everything in my power to get this to work (I need this for my master thesis)
