Comment (by BjarneDMat):

 @chrstphrchvz I've got `mariadb-10.5` running on 10.6 Snow Leopard

 @kencu So in order to -possibly- get mysql8 to compile under 10.6 Snow
 Leopard, one has to install `libc++` eg like this :\\
 port -cuNp upgrade --enforce-variants libcxx +emulated_tls -universal
 +replacemnt_libcxx\\
 #=> find /Developer -name 'libc++.dylib'\\
 /Developer/SDKs/MacOSX10.6.sdk/usr/lib/libc++.dylib

 Having done that, mysql8 @8.0.23 fails to compile
 log here : https://macports.mathiesen.info/logs/databases/mysql8/main.log3

 According to https://mariadb.org/wp-
 content/uploads/2020/09/migration_serverfest2020.pdf slide #9, there's no
 current mariadb equivalent to mysql8
