cp: cannot stat 'conftest.py': No such file or directory

Steps To Reproduce

On Linux Mint 22 and Python 3.12, trying to run pip install sage-conf in a fresh virtual environment, I get:

Collecting sage-conf
  Using cached sage_conf-10.7.tar.gz (2.6 MB)
  Installing build dependencies ... done
  Getting requirements to build wheel ... done
  Preparing metadata (pyproject.toml) ... done
Building wheels for collected packages: sage-conf

      ./configure: 3: ./real_configure: not found
      mv: cannot stat 'bak_conftest.py': No such file or directory
      configure failed; this may be caused by missing build prerequisites.
      You can install the required build prerequisites using the following shell command
      
      sudo apt-get install binutils make m4 perl flex python3 tar bc gcc libbz2-dev bzip2 g++ ca-certificates patch pkg-config xz-utils libffi-dev
      
      error: configure failed
      [end of output]
  
  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for sage-conf
Failed to build sage-conf
ERROR: Could not build wheels for sage-conf, which is required to install pyproject.toml-based projects

sorry, what are you trying to do by running pip install sage-conf ?

[jack-jjm]

Well, that's one of the recommended ways to install Sage, right?

[dimpase]

oops, yes, this is an obsolete doc, sorry.
@tobiasdiez - do we plan to resurrect this?
If not we should have removed this doc.

[tobiasdiez]

No, this is absolutely outdated.

We do should add a "install from pip" section in the installation instructions, mostly similar to https://doc-develop--sagemath.netlify.app/html/en/installation/meson#building-from-source-using-meson.
