 The value actually used was none. The empty string. MacPorts believed that
 no compiler that satisfied the requirements of the Portfile, specifically
 C++20 compatibility. According to the code, that should require Apple
 clang 15 or llvm.org clang 16 or gcc 12 or later. Not sure why it doesn't
 select clang 16 on Snow Leopard. We see the same failure on the i386 and
 x86_64 Snow Leopard buildbot machines.
