I am trying to work with the jitter tutorial # 41 ‘shaders’
I get the following error message:

ERROR: 0.26: ‘assign’ : cannot convert from ‘4-component vector of float’ to ‘varying 3-component vector of float’
•error:–END GLSL INFO LOG: vp —
•error: jit.gl.shader: GLSL program failed to compile.
I am on a last generation powerbook 15" 1.67Ghz
ATI Mobility Radeon 9700 – VRAM (Total):128 MB
2 monitors – laptop and "Studio Display 21"
