Hey,
 
I am trying to install Sage into my python venv following the installation instructions from the README.
 
However, it keeps failing on the (sage-venv) $ python3 -m pip install -v sage_conf step.
I get the following error message: 
 
cp: conftest.py: No such file or directory
  ./configure: line 3: ./real_configure: No such file or directory
  mv: rename bak_conftest.py to conftest.py: No such file or directory
  configure failed; this may be caused by missing build prerequisites.
 
I am using Python 3.11.9 and pip 25.0.1 but I have also tried with Python 3.13.3 and got the same error message.
 
I am on macOS Sequioa Version 15.4
 
The error message tells me that: 
 configure failed; this may be caused by missing build prerequisites.
  You can install the required build prerequisites using the following shell command
  brew install bzip2 xz libffi
 
But I have these packages installed.
 
When I check in the .sage folder I see that conftest.py is indeed missing.
 
Best regards
