  It looks like you're compiling on Linux and also targeting Linux. Currently this
  requires the `pkg-config` utility to find OpenSSL but unfortunately `pkg-config`
  could not be found. If you have OpenSSL installed you can likely fix this by
  installing `pkg-config`.

I tried with the environment variable: RUST_BACKTRACE=1 and did not notice any different output.

The file throwing this error is from:
/home/coder/.cache/Homebrew/cargo_cache/registry/src/github.com-1ecc6299db9ec823/openssl-sys-0.9.74/build/find_normal.rs

    if host.contains("unknown-linux")
        && target.contains("unknown-linux-gnu")
        && Command::new("pkg-config").output().is_err()
    {
        msg.push_str(
            "

        );
    }

So this must be true: Command::new("pkg-config").output().is_err()

Resolved by installing pkg-config through apt instead of brew.

ie:

sudo apt install pkg-config

Note: I did not remove pkg-config from brew.

PS: Not sure if something changed between these versions that provoked this?
