main.log from Snow Leopard, Mac OS X 10.6.8

[ken-cunningham-webuse]

qt5 cannot build on Mac OSX 10.6.8 at present, and 5.6.2 almost certainly never will. Perhaps, with luck, some earlier version might be forced to build someday.

[MarcusCalhoun-Lopez (Marcus Calhoun-Lopez)]

I fooled around with this for quite a while, but I can not find a way to fix it.
All the way back to 5.3, Qt uses ​CFRunLoopTimerCreateWithHandler, which was not introduced until 10.7.
