Hi Gerard,
how about an alternative way to deal with this?
1. draw the text with Inkscape (put text on a path);
I think there is even a tutorial for this.
2. select the graphic and save it as *.eps
3. use pstoedit to convert it into *.mp
pstoedit -v -ssp -f "mpost:" foo.eps foo.mp
4. edit/scale the metapost graphic as you like
Best wishes, Peter
