Warning compiling the training courses (iPhone)

I am using the latest PowerVR SDK for iPhone (2.06) with Xcode 3.2.2, and am getting warnings like the following when building the training courses:

PVRTMat4::PVRTMat4() has different visibility (default) …/libOGLES2Tools.a(PVRTVector.o) and (hidden) in …/OGLES2IntroducingPOD.o.

I’m getting the same warning in my own projects. Anyone know how to get rid of them?

I have the same annoying problem!
