Thanks for the documentation :)

No. Only some very simples ld.so.config in /etc/ld.so.conf.d

I tried yesterday I works as expected on a Xubuntu 16.04 machine without 
guix installed on it.

Don't have much time to investigate on it.

For information, it's a CentOS 7.6.1810 server which I did not configure 
from the beginning, so I don't know precisely which changes has been 
made on it...

I think, maybe there is a conflict of another libQt5Core (not 5) 
installed on the machine ?

Anyway, thanks for your help,

Andréas
