I think the issue is that perl gets built with a newer clang, so it sees that -fstack-protector-strong works and that fact gets baked into the perl configuration files that get installed. Then it tries to use this flag when building perl modules, even if the perl module is built with an older compiler that doesn't understand that flag.

Josh tried to address some of this problem in [f35a2c53331234cc730b090b1b866d4b1702a747/macports-ports] but it only covered specific flags, and didn't include this one. I'm not sure what the right solution is, other than explaining to the perl developers yet again the folly of their assumption that the compiler that's used to compile perl will be the same compiler used to compile all modules.

[jmroot (Joshua Root)]

This is an odd corner case where the port is noarch but is running a compiler during its build process. For noarch ports, compiler.cxx_standard defaults to nothing, which will affect compiler selection. The easiest workaround may be to set compiler.cxx_standard 1998 to match the default without noarch.

p5-alien-gmp: pick compiler as though not noarch
