The following is the response from the port maintainer about the issue
noted above:

Thanks for reporting.

The issue here is that a header (ucontext.h) refers to size_t without
having included it explicitly. ucontext.h should probably have used
the internal name __size_t instead of size_t. The patch at [1] is a
quick fix to that problem. (Please note that this is not an issue in
Lua’s implementation, but in a header that it transitively includes.)

Let me know if that fixes the issue!

Cheers,

I will test this patch today at some point.
Cheers,
Russ
