Reproducible Example
# in an environment where numpy fails to be imported because for example libstdc++.so.6 doesn't exist
import pandasIssue Description
I was importing pandas in an environment where libstdc++.so.6 could not be found, which causes numpy to fail to load its C++ extensions.
The error I got was the following:
Traceback (most recent call last):

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!
Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.
We have compiled some common reasons and troubleshooting tips at:
https://numpy.org/devdocs/user/troubleshooting-importerror.html
Please note and check the following:
* The Python version is: Python3.12 from "/home/nora/projects/rplcs-events-tournament-1/.venv/bin/python3"
* The NumPy version is: "2.2.3"
and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.
Original error was: libstdc++.so.6: cannot open shared object file: No such file or directory
The above exception was the direct cause of the following exception:

Expected Behavior
Pandas printing the full error, including nested exceptions.
Installed Versions
It can't run it because my environment is broken, but I can see the relevant code on master. Pandas version is 2.2.3
