What to do about warning messages about packages not being used by the installed Perl interpreter

[locuaz]

when updating the system I’m getting this warning message:

WARNING: '/usr/lib/perl5/5.32' contains data from at least 1 packages which will NOT be used by the installed perl interpreter.
 -> Run the following command to get a list of affected packages: pacman -Qqo '/usr/lib/perl5/5.32'

Then I run these commands:

$ pacman -Qqo '/usr/lib/perl5/5.32'
perl-goo-canvas

~ 
$ sudo pacman -Rsn perl-goo-canvas

When deleting those packages I don’t know how my system will be affected. What should I do?

Remove it. This package is not in the repository and not in the AUR.

It was in the AUR, but got removed form the AUR. Since it was build against an old Perl version, it will fail anyway.

If you interested, try to find out why you installed this AUR package. Check the pacman.log.
