Fail to compile cargo-c v0.9.27+cargo-0.74.0 using Rust 1.76.0

My project is still using Rust 1.76.0, and I'm currently targeting cargo-c 0.9.27 that used to be compatible with my toolchain version.

However since yesterday:

To reuse those artifacts with a future compilation, set the environment variable `CARGO_TARGET_DIR` to that path.
Caused by:
  package cargo-util v0.2.12` cannot be built because it requires rustc 1.77 or newer, while the currently active rustc version is 1.76.0
  Try re-running cargo install with --locked

cargo-util 0.2.12 has been released yesterday and it requires at least Rust 1.77.0. Should cargo-c fix a specific version of cargo-util since it can introduce breaking changes ?

You'll have to make use of the Cargo.lock that cargo-c 0.9.27 was released with, or get a fixed cargo (see rust-lang/cargo#13873 etc).

you can use cargo install --locked or run cargo update --precise passing the correct cargo-util version you want.
