WooHoo! That fixed the problem! "mpost > data.mp" runs to completion, and it also works when run from inside xTherion.
That suggests a packaging bug in some tex/metpost package on fedora, which should have run that as a post-install action. This would be good to isolate/report, but without being (becoming :-) a tex/metpost geek you made find this hard to track down.
