The erros seems to be that instead of getting (./mptextmp.mp)
(./mptextmp.mp) (./mptextmp.mp)

you get this:

(./mptextmp.mp
>> mptextmp.mp
>> mptextmp.mpx
! Unable to make mpx file.
l.2 btex
         \mainfont 0 etex
The two files given above are one of your source files
and an auxiliary file I need to read to find out what your
btex..etex blocks mean. If you don't know why I had trouble,
try running it manually through MPtoTeX, TeX, and DVItoMP

So ./mptextmp.mp is falling over. I failed to work out from peering at
the sources exactly what the metpost command therion issues is, and
thus how to test it manually.

I did notice whilst investigating that thmpost.cxx is nothing but a
massive const char * string defintion of the whole metapost file,
which seems pretty crufty. This is presumably the very old bring
'inline' of the tex and metpost stuff to avoid issue with Windows
people having files missing/not found. I would like to understand how
this stuff works, for debug and also for considering whether it is
worth undoing so that the files can be placed more normally/correctly
in the Debian packaging.
