I was unhappy about my Perl installation. I was getting a warning regarding XS. Some of the libraries I had installed were compiled for a different version of Perl. Sure, I had installed Perl modules using `cpan` and `cpanm`. Apparently I had received a new Perl via an upgrade of PureOS. Sadly, I didn’t know how to quickly find all the modules which included XS and reinstall and recompile them.
Here’s a start:
find $(perl -e 'print join " ", @INC') -name XS.so
But then again... Perhaps it would make more sense to use `perlbrew`. It’s what I use on my server. Just ignore the system Perl!
But it also involves a lot of downloading and installing of Perl modules... That’s not cool. So perhaps I should continue using the system Perl and just try and replace all the packages I had installed with system packages? Let the package manager handle it?
Sadly, I immediately ran into the missing package `Mastodon::Client`. And once you try to install it, it pulls in all the dependencies. Some of them I might have installed using the system package manager, but `cpanm` doesn’t know about that.
So back to `perlbrew`, right? And I can delete all the system Perl modules...
Get the list:
apt list --installed "*-perl" | grep -v automatic | sed 's/\/.*//'
And run the command:
sudo apt remove libcaptcha-recaptcha-perl libcapture-tiny-perl \ libcrypt-random-seed-perl libcrypt-rijndael-perl libdatetime-perl \ libdatetime-timezone-perl libhtml-template-perl libhttp-date-perl \ libhttp-server-simple-perl libjson-perl liblist-allutils-perl \ liblocale-gettext-perl libmce-perl libmldbm-perl libmodern-perl-perl \ libmojolicious-perl libnet-server-perl libnet-whois-parser-perl \ libpod-strip-perl librpc-xml-perl libtext-charwidth-perl libtext-iconv-perl \ libtext-markdown-perl libtext-wrapi18n-perl libtime-parsedate-perl \ libxml-atom-perl libxml-libxml-perl
Whatever, right? Enter! Enter!
But wait... what’s this? This is *all wrong!*

Nooooooo! It took so long to abort the operation, now it’s all borked, surely.
OK, how to I recover from this?
apt install evince inkscape gnome pureos-standard perlbrew aspell-de
I hope? Wish me luck!
Fist, switch to a stable Perl using `perlbrew` and get the modules installed. At this point I’m just trying to finish the task I set out to do, hours ago.

And I think I’m back! Restarted the system and no problem. Emacs works. Browser works. Phew! 😅

Oops!
For what it’s worth, I prefer to package any missing libraries as `.deb` packages myself and install them. `dh-make-perl --cpan MODULE` makes this easy, usually.
(If you need much newer versions of modules, especially “low level” ones, it might not be feasible to go this way, though.)

Oh, interesting! Thank you for the suggestion.
