That ticket and all of its duplicates were only experienced by users on macOS Catalina who had failed to update their command line tools to a Catalina-compatible version; therefore no further investigation was planned. Learning that Snow Leopard is now affected as well would be a significant new detail. Maybe it has been caused by MacPorts base recently switching to using a newer MacPorts clang on 10.6 and other older systems.

Did you mean Core Duo? Core Duo and Core Solo systems are limited to 10.6.8 maximum, but Core 2 Duo system should be able to upgrade to at least 10.7.5.

Graphviz built successfully on 10.6.8 last time we tried to do so on December 26; see the port health indicators:
In MacPorts, 10.6 and later use libc++, but since 10.6-10.8 don't default to libc++, some ports have bugs that cause them to fail to build on 10.6-10.8 due to stdlib mismatch (such as failing to supply the MacPorts-specified CXXFLAGS to the build system); in that case, these bugs should be fixed. I don't think that's the case here, because, grepping through Greg's log, every invocation of clang++ does indeed already have the required -stdlib=libc++ argument.
