Comment:

 It might be something glitchy/weird with your local cargo setup on the
 Mac? Maybe try doing `cargo clean` in the protover directory and running
 `make test-rust` again? Also, possibly your lockfile has something weird
 going on, so maybe if that doesn't fix it, try `rm src/rust/Cargo.lock`
 and running again?
