Oh right sorry.
I think I see what's happening.
Since https://github.com/coreutils/gnulib/commit/4db8db34
gnulib has been unconditionally replacing lseek() on macos.
Now with SEEK_DATA undefined that replaced lseek()
will run the code intended for BeOS.
So either the lseek.m4 or lseek.c needs adjusting accordingly.

cheers,
