Failed to parse file devel/game-porting-toolkit/Portfile: can't read "configure.cxx_archflags.": no such variable

You’ve tagged the wrong person, I’m maintainer of this port.

If you look over the Portfile you’ll see that configure.cxx_archflags isn’t set anywhere.

You need to provide debug output and some info about your system configuration in cases like this where there is no log. The debug output will have a backtrace that shows exactly where the error is happening.

Based on the variable name and your hardware of choice, I can only assume this is probably happening in muniversal on systems that can't run x86_64 code.

presumably related to the portfile setting this

muniversal.arch_flag        no

and then going down some previously-untested code pathway on your system….

This appears to happen any time build_arch is not either arm64 or x86_64, and also affects wine-stable and wine-devel.
