"make" error when trying to install version 6.0.0 under macOS Sonoma 14.4.1:
config.log is attached. Below is portion of output to Terminal during "make".
Issue seemt to be the C++ compiler. I have the MacPorts gcc13 installed. Unfortunately, the MacPorts gcc11 reports as "known to fail" if I attempt to install it.

It appears from the log you attach that your /usr/bin/gcc is really pointing to a clang compiler, not to gcc13.
I don't know whether that is normal on a Mac or not, but perhaps it would solve your problem to predefine both CC and CXX environmental variables to point to the actual gcc compiler rather than to clang.
Alternatively your clang compiler may work if you add the compilatation flag
-std=c++17
. I have had to do that for some clang versions in the past. I have usedsetenv CXXFLAGS "-std=c++17 -Wall -fPIC"
