It also needs a fix for AI_NUMERICSERV like in: 976522a

Otherwise:

scamper_control.c: In function ‘remote_connect’:
scamper_control.c:3801: error: ‘AI_NUMERICSERV’ undeclared (first use in this function)
scamper_control.c:3801: error: (Each undeclared identifier is reported only once
scamper_control.c:3801: error: for each function it appears in.)
make[2]: *** [scamper-scamper_control.o] Error 1
make[2]: *** Waiting for unfinished jobs....

If you could add a patch here, it would be great (as it also relates to < 10.7).

Thanks, I can do. Is there a howto on testing ports on older OSes?

[barracuda156]

@matthewluckie Not really, I guess. It is fairly easy to install pretty much any macOS version in a VM though on an x86_86 hardware. (Building for PowerPC would require everything from scratch, but otherwise pre-built ports are there.) Also port status will show failures on buildbots (if any), so that can be used to see if builds work (since no buildbots for < 10.6 or any PowerPC, those can’t be checked this way).

@barracuda156 This is provided by legacy-support, so shouldn't this port just use the legacysupport PG?
