Leo, The autowrap tests should only fire if you have numpy installed. So I'm guessing that you do. But it doesn't seem to find the numpy header files. You'll need Cython too. Do you have all the dependencies installed for the autowrap module? We haven't had any testing of this on Mac or Windows,

Some notes: - Since you specified your kinematic relations as u = q', then you should set your velocities with u instead of q, for example: p1.set_vel(N, u1d * N. x) - I doubt that you need to specify any velocity constraints and thus you will not have any dependent speeds. You've defined ell as
