I don't know, but from the message it looks like some 'local' variables
is not saved and defined. I'm surprised that loading some mf file works
at all (because it also assumes some mf related definitions). I also hav
eno clue if such a package adopts 'core' metafun code (and mpiv metafun
is different from mpii).
Fonts are in /fonts/source/public in a TeX Live distribution, in case it helps.
