OK. That makes sense.

Well, in the log snippet I provided, the implication is: Success.

There's no luac in the Cray SDB images by default, only the
supporting libs, as the functionality is clearly there, vis:
the very first loading had already picked up a "missing end",
hence the assumption that the Success seen was implying a
"deep joy".

Will keep playing: cheers for the info,
