You should file a bug report in Trac. :) I see you're one of the maintainers of the port but that's still the correct place to report build failures, and if you need help resolving it you can ask people on the list to view the bug report and comment there.

legacysupport adds some (but not all) of the clock_gettime-related functionality that was added in macOS 10.12. Since you are seeing build failures on 10.14 and earlier, this is different.

clock_serv_t for example is defined on my High Sierra system in /usr/include/mach/mach_types.h. mach_port_deallocate is declared in /usr/include/mach/mach_port.h. mach_task_self is declared in /usr/include/mach/mach_init.h. Maybe this code just isn't including those headers, or whatever other system header that includes them is the canonical one to include to get this functionality. (I can't find Apple manpages for these functions, which would usually tell you what header you need to include.) Maybe on Catalina and later, coincidentally some other system header is now including it, which is why the build succeeds on newer systems.
