haha, I was expecting some convoluted API-version incompatibility issue
but I just did not have LPeg 5.3 installed... installing the library
fixed the issue, thanks.

While searching for the source of the issue I was wondering about how to
handle error reporting in vis the best way.

I came up with only two general approaches. Either send error messages
to the UI (including a sleep() so that errors further down in the call
chain don't get eclipsed) or log them to a file (both approaches feel like
bad choices). I wonder how other TUI programs handle their error messages.
