My setup: macOS 15 Sequoia Beta 3, MacTeX 2024, ARM processor. More precisely:

	% uname -v
	Darwin Kernel Version 24.0.0: Mon Jul  1 21:58:28 PDT 2024; root:xnu-11215.0.132.501.1~1/RELEASE_ARM64_T8103

First I ran the script from a test directory on my desktop, using "./extractbb.lua --version". Then I realized the output was useless, since you compare the script directory and kpathsea's output.

Here's what I get with the scripts installed in /usr/local/texlive/2024/texmf-dist/scripts/:

	% extractbb --version

	The ffi module is available for:

	    archictures       : ARCH_X86 and ARCH_X64,
	    operating systems : OS_CE, OS_WIN, OS_LINUX, OS_BSD and OS_POSIX

	The ARM processor is currently not supported. There are subtle
	differences between this module and the one in luajitTeX  and we hope to be in sync around TeXLive 2022.
	Different OS can have different interfaces,
	for instance OS_WIN has not 'complex.h'. If you want portable
	code, stick to the most common concepts.
	! extractbb ERROR: The script is in an incorrect location.

	Technical Details:
	kpse_script_path: (string) /usr/local/texlive/2024/texmf-dist/scripts/texlive/extractbb.lua
	resolve_interpreter_name: (string) texlua
	os_type: (string) unix
	exec_interpreter_dir: (string) /usr/local/texlive/2024/bin/universal-darwin

	resolve_script_path: (string) /Library/TeX/texbin/extractbb
	exec_script_path: (string) /Library/TeX/texbin/extractbb

	stack traceback:
	/Library/TeX/texbin/extractbb:320: in main chunk

Forcing the script to run in Intel mode through Rosetta 2 emulation, not only the ARM warning disappears, but also things change completely:

	% arch -x86_64 extractbb --version
	(Wrapped by extractbb.lua $Revision: $.)

	This is extractbb Version 20240407

Better try on an actual Intel Mac, the above may be due to the way Rosetta 2 works. Unfortunately I'm away from home, on very slow ADSL (5 Mb/s). I have access to an old Intel Mac with macOS 10.15 Catalina, on which MacTeX 2024 can be installed, but it will take hours to download. I'll report as soon as that's done.
