As you most likely know the FD cage should be approx parallel with the rings. I cannot tell from the pictures for sure if that is the case. If the cage is at an angle then adjusting it to be parallel may be the solution.

That out of the way I suspect that the Ritchey crank may be the problem. It may not allow enough space for a modern cage. How large is the gap between the top of the large ring and the inside of the crank arm? That space has to be wide enough to allow the cage to move over. Sometimes parts from different decades (centuries?) don't play well together.
