It doesn't work because POV-Ray sees the "MySpline", decides that you are
declaring "SplinePoint" as a spline, and gets confused when it finds "("
rather than ";" or "{".  The workaround is:

#declare SplinePoint=<0,0,0>+MySpline(clock);

This tells POV-Ray that you are declaring SplinePoint as a vector.

I think it's the same problem.  I could be more certain if you had posted
the error message.
