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
