It builds a white cube but seems > unaffected by the rest of the code. yes, the problem is with (build-cube). you build a cube, which places a cube in the scene. then you draw a cube, which is placed on the same spot, but because of the z-buffer it does not get drawn. delete the (build-cube) and it should work.
