ctranslate import error on modern Linux

[Keridos]

I installed via install CPU script (commit 91f1c3a. Installation works fine.
However ctranslate fails to be imported on my arch linux machine.
Googling the error lead to whisperx related posts mentioning glibc (my version: 2.41+r48+g5cb575ca9a3d-2) had a change that broke ctranslate.
Downgrading glibc is a surefire way to brick your system, so I did not do that.
Providing a dockerfile for CPU could probably enable it to work properly.

Below the call of the script and the error trace
