Comment (by buck):
I believe I've fixed the `ValueError: unknown prototype character 'b'`
issue. Pari recently added the concept of "bit precision", which (I
believe) is the natural precision format in sage, so needs no conversion:

There's again a further issue that I don't understand yet:

On brief inspection, I don't see that the number of arguments should have
changed.
