I believe atomics is in Xcode 7 and later and your OS supports up to Xcode 5, so I don't think it's possible to build mpv there. A earlier version might build fine but mpv is already hard to maintain with only one version.

Has duplicate #63753.

Atomics are a feature of the compiler, no? So it should be buildable on older systems by using a newer compiler, which MacPorts will do automatically due to [8222cfaa4124483d2faad4f35a209885d440dd61/macports-ports] (which was committed months before this ticket was filed...)

We do already show successful builds on the buildbot on Snow Leopard, and I filed a PR today to fix build failure on Lion, so building on older systems should work fine. There is still an open ticket about a build failure on Mavericks which needs a separate fix.
