This issue is partially for my own note.
larsbrinkhoff commented 7 years ago

Sorry, I haven't done much work to merge in changes from everyone, so this isn't expected to work.

larsbrinkhoff commented 7 years ago

I merged in some changes to make it work in BSDs. It should probably be better now. But there's nothing specifically for OS X... I mean macOS.

b4 commented 7 years ago

Builds now.
