I then set GCC 14 as compiler to build (instead of Clang 17.0.6). The result is:

make[2]: *** [src/libcksum_avx512_a-cksum_avx512.o] Error 1
Is this more of an assembler problem? Installed are:
/usr/bin/as Apple LLVM version 10.0.0 (clang-1000.11.45.5)
/opt/local/bin/nasm NASM version 2.16.03 compiled on May 17 2024
/opt/local/bin/yasm yasm 1.3.0
no gas
To determine which assembler is used I added "-Wa,-v" to CFLAGS and got:
Apple LLVM version 10.0.0 (clang-1000.10.44.4)
Target: x86_64-apple-darwin17.7.0
