Unable to install pglookout-2.0.2.tar.gz on Rocky 9.2 Linux server with python39 version

Hi Team,

I am trying to install pglookout-2.0.2.tar.gz on Rocky 9.2 OS where we have python39 installed:

`python3-3.9.16-1.el9_2.2.x86_64`
```

> python --version
> Python 3.9.16

```

Setuptools version installed in the server is:
```
rpm -qa | grep python3-setuptools
python3-setuptools-wheel-53.0.0-12.el9.noarch
python3-setuptools-53.0.0-12.el9.noarch
```
While trying to install pglookout i am getting the below error:

> /usr/bin/python3.9 -m pip install pglookout-2.0.2.tar.gz
Processing ./pglookout-2.0.2.tar.gz

```
python3.9 -m pip list | grep setuptool
setuptools 53.0.0
python3.9 -m pip list | grep pip
pip 21.2.3
```

I have a higher version of setuptools , but still it keeps looking for setuptool version. Any suggestion would be helpful
