I'm getting the same error with the just committed cargo 0.13.0 and rust 0.12.0.
This surprises me a bit, because it means the rust maintainers seem to not have this problem. So it must be something on our systems that's causing this failure.

[Comment 2 Dirkjan Ochtman (RETIRED) 2016-09-30 18:55:25 UTC]

According to upstream, this could happen when you're installing cargo-0.12.0+ with rust older than 1.9.0. cargo-0.13.0-r1 now depends on >=rust-1.9.0. Please give it a shot!

[Comment 3 Harris Landgarten 2016-09-30 19:23:43 UTC]

I am using dev-lang/rust-1.12.0 and still getting the same error

[Comment 4 Hanno Böck 2016-09-30 20:41:35 UTC]

Same here (rust 12, still seeing the error), but now I know what's going on. I still had rust-bin installed and that's still at 1.8.0.

So for all people seeing this: You can fix it by uninstalling rust-bin and afterwards running "eselect rust set 1".

Still for bootstrapping reasons rust-bin should be bumped, I've created bug #595720 for that.

[Comment 5 Harris Landgarten 2016-09-30 21:06:52 UTC]

I can confirm uninstalling rust-bin fixes the issue
