Describe the problem

This seems to be introduced from #3218. cc @pcmoritz

I think that line with 10.7 was added by @pcmoritz in #3218 to make it build on MacOS 10.14.

Note that we're seeing a similar error (but with 10.9 -> 10.14) in this comment https://github.com/ray-project/ray/pull/3218/files#r231489034 from @raulchen.

@pcmoritz do you know we actually need to set MACOSX_DEPLOYMENT_TARGET somewhere else as well (perhaps to 10.7)?

@lucfisc Can you try if this fixes it for you? #3337
