Errors during plain setup

Hi
I have a clean Debian 11 where I'm trying to run the setup script.
I noticed a lot of errors. For example, at the end:

but I'm not sure there aren't any other errors (I noticed many errors compiling freeswitch), and this kind of problem on a clean setup is really strange
