Not sure what the fix should be, but I just saw this while building on OSX:

This documentation states that Apple has deprecated this functionality purposely on their lib, and it would be replaced by launchd.

I will have to look into this more.

FWIW -- my two cents here is that I sort of doubt they will actually remove this... since it's been a BSD function for ~30 years. They just don't want people using daemon() or anything that forks because their Apple libs break when you fork. :/
