[BUG]Mandatory virutal environment for python makes the configure script fail

[Boorhin]

🐛 Bug report

Description of the bug
In new Linux kernels (I am on Ubuntu 24) All user installs should be within a virtual environment. However scons install uses a --user flag which is incompatible with venv (recommended). I tried both within and outside a virtual environment and both crash the madagascar configure install script

To Reproduce
In Ubuntu 24.04 or similar kernel run ./configure within a virtual environment and outside.

Expected behavior

Install scons within a virtual environment

Screenshots

Desktop (please complete the following information):

• OS: Ubuntu
• Version 24.04
• 6.14.0-37-generic

** Additional comments
in the configure script a test for a virtual environment should be performed or an advice to install scons in the virtual environment before?

(venv) $ pip install scons
