Ups!

The functionality has been greatly reorganized and optimized in May
last year. But since the developer doesn't use LaTeX and LaTeX users
don't upgrade their TeX distributions (there is noone to blame since
it is indeed a bit tricky to do so, and LaTeX users usually have no
need to), this part remained untested until now.

If you want a temporary solution, use

verbatimtex
\def\fett{\ss\bf}
\def\mathcal#1{{\cal#1}}
etex

instead of what you have now and running
    mptopdf zScaled.mp
should suffice (no need to run mpost separately).

But this behaviour should be fixed.
