Unable to Build Qt Scenegraph

First post here, I’m entirely new to the Qt world; sorry!
I'm having trouble with Qt Scenegraph.

I built Qt 4.7 from git with ./configure -opengl (using gcc version 4.2.1 - Apple Inc. build 5659)

Qt3D compiled flawlessly and yet I get the following errors when running make for Qt Scenegraph:

Code:

Any help in the right direction is greatly appreciated!
