However, note this warning:

warning: `#[derive]` for custom traits is deprecated and will be removed in v1.15. Prefer using procedural macro custom derive

   |                            ^^^^^^^^^^^^^^^^

So this is something of a last gasp for num-macros, and we'll have to kill it soon.

My own testing used the same as the initial Travis build here:

$ rustc --version
rustc 1.15.0-nightly (2217bd771 2016-11-25)
$ cargo --version
cargo 0.16.0-nightly (b26d672 2016-11-25)

The failing homu builds are using:

$ rustc --version
rustc 1.15.0-nightly (03bdaade2 2016-11-27)
$ cargo --version
cargo 0.16.0-nightly (3568be9 2016-11-26)

I updated locally, and now I see the same SSL errors. :(
