Same here, the issue is that the crate dependencies should be updated. https://github.com/sfackler/rust-openssl/issues/521 FWIW I've been using cargo 15 with the crates listed in this ebuild: https://github.com/Wonko7/w7-overlay/blob/master/dev-util/cargo/cargo-0.15.0-r1.ebuild And this builds and works with libressl. I didn't submit a patch request because I'm not a rust guy and not sure if I've introduced nasty things by doing that.
https://github.com/Wonko7/w7-overlay/blob/master/dev-util/cargo/cargo-0.16.0.ebuild This works with libressl, I just updated the crates.
This should be fixed in cargo-0.21.0, feel free to reopen if it doesn't work for you.
