Comment (by kencu):

 also, miraculously perhaps, upstream has fixed support for <= 10.9!

 https://github.com/rust-
 lang/rust/commit/dc38d87505f4b1e381f143b4f34704df6a24e57e

 So once we have a version that includes that commit, all our rust
 workarounds can go away. It appears 10.6 and less will be forever
 unsupported, but that is life.
