macOS built Python3.11b5 can't find lib-dynload in relocatable framework if framework is relocated and python run from external symlink

Bug report

A build of Python 3.11b5's fails to find lib-dynload path if the following normally ok combination of criteria are met:

• The framework is made or modified in such a away to be relocatable (dynamic links are relative using @loader_path, etc) instead of absolute path
• The framework is installed in a location it wasn't built at
• python is executed by a symlink from elsewhere

Your environment

To reproduce this easily, I decompressed the installable package into my home directory, making a framework structure that would normally run. I do have to modify the linking to work relocated, using the following commands:

 install_name_tool -change /Library/Frameworks/Python.framework/Versions/3.11/Python @loader_path/../Python Python.framework/Versions/3.11/bin/python3.11
 install_name_tool -change /Library/Frameworks/Python.framework/Versions/3.11/Python @loader_path/../../../../Python Python.framework/Versions/3.11/Resources/Python.app/Contents/MacOS/Python

I then symlink the python executable.

ln -s Python.framework/Versions/3.11/bin/python3.11 python3.11

the following command works fine

./Python.framework/Versions/3.11/bin/python3.11 -c "import math"

while this does not

 ./python3.11 -c "import math"
Could not find platform dependent libraries <exec_prefix>
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'math'

even though the shell itself works normally, just the lib-dynload is not being found.

I can make it work with the attached patch, but I don't assume it is the correct way to fix it
relocated_framework.patch.gz
.

Commencez par reproduire les commandes d’exécution directe et de symlink externe sur macOS, en comparant l’importation réussie avec le cas où lib-dynload est manquant. Examinez ensuite le fichier joint relocated_framework.patch.gz ainsi que la gestion du démarrage et des chemins du framework qu’il modifie. Le travail est terminé lorsque l’importation de math fonctionne quand le framework déplacé est exécuté via le symlink externe.
