[gibix]

seems a network problem, the bug is still present?

[gentoo90]

I digged a little and found out that it's a sandbox issue.

FEATURES="-network-sandbox" emerge =dev-util/cargo-9999

works fine. But there should be a way to make it work without disabling the sandbox.

[gibix]

I just emerged cargo-9999 correctly. Are you ussing a particular env?

I just emerged cargo-9999 correctly.

I was able to emerge it some time ago, but now it's broken, after some update of portage I suppose.
Do you have network-sandbox in your FEATURES?

[gibix]

no, but network-sandbox is not on by default, maybe you have it in some conf
