Yes, I suppose I could just delete it. However, my comment is "also" that
at 8.15 it packaged fine. Starting with 8.17 (or maybe 8.16, I can download
and try).

FYI - I can execute the program [ (as ./? --version as the shell does not
like [ entered directly, and I am not counting the backslashes correctly).
So, maybe your sample program would execute. I will try it in a day or so,
just checking mail for now.
