Lualatex problem with Win32 binaries in TeXLive installed under macOS

[John Collins]

Thanks, David.  That was of course the problem.  I just needed to know where to 
look. The TeX Live bugs and updates pages has the information.

Karl's trick with TEXMFSYSVAR_lualatex solved the problem nicely.  (If I set 
that environment variable, then running lualatex was enough to cause the .fmt 
file to be made, which seemed pretty slick to me.)

Obviously, it would be nice not to have to resort to this trick (for the small 
number of us who share TL installations between OSs). So here's hoping for TL 
2023.
