[Therion] Need metapost wizard: new text label

Interesting ... I am using it myself and it works here. I wonder if
there is something odd in what the wiki outputs. Or maybe you copy &
pasted the "code metapost" inside an existing "code metapost" block. If
you have time to check, what's your error message?

Or alternatively, do you have a minimal survey where I can see the
failure myself?

I won't pretend to understand what that is all about. Very weird indeed.
