Since MetaPost processes TeX material on a per-file basis, the 
verbatimtex  in one file will not be available to the btex in the 
other file. So even if the path problem were worked out, this 
example would still have problems if the input file used any 
latex macros not available in plain tex.

Still, mpost should at least be able to run its mptotex  process
unless openin_any is set to r or p. It seems the failure happens in
that process:  no .tex file is produced  (under -debug it would 
remain, and there is none).

It would be a help for debugging if it were possible (as it used to be) 
to run mptotex (or mpto -tex) separately. Perhaps with an option  to
mpost like dvitomp? Note that there is still a message in the .log file 
advising one to try running mptotex after such a failure.

I may have said all this before.
