To fix this, we can use our system's `sudo` command and the `chown/chmod` commands to give our newly-built `sudo` the permissions it needs:

> cd (built-products-directory)

> sudo chown root:wheel sudo && sudo chmod 4755 sudo
```sh
cd (built-products-directory)
sudo chown root:wheel sudo && sudo chmod 4755 sudo
```

Now if we try running our copy of `sudo`, it should work:

> cd (built-products-directory)

> ./sudo -s
```sh
cd (built-products-directory)
./sudo -s
```

If you don't have a Mac with a biometric sensor, `sudo-touchid` will fail. If you'd still like to test whether the `LocalAuthentication` framework is working correctly, you can change the `kAuthPolicy` constant to `LAPolicyDeviceOwnerAuthentication` in `sudo/plugins/sudoers/auth/sudo_auth.m`.

Instead of replacing `sudo`, we can install our build under `/usr/local/bin` and give the path precedence over `/usr/bin`, this way our build is found first.

> sudo cp (built-products-directory)/sudo /usr/local/bin/sudo

> sudo chown root:wheel /usr/local/bin/sudo && sudo chmod 4755 /usr/local/bin/sudo
```sh
sudo cp (built-products-directory)/sudo /usr/local/bin/sudo
sudo chown root:wheel /usr/local/bin/sudo && sudo chmod 4755 /usr/local/bin/sudo
```

You can set up your `PATH` by adding `export PATH=/usr/local/bin:$PATH` to `.bashrc` (thanks @edenzik).
