I think it is quite simple you need to install `perlbrew` [here](https://perlbrew.pl/)

You then run the software under perlbrew it should work.

At present you are running the system perl5 and that is causing all sorts issues, for example the age of the installation and the fact system operations and your software are using the same version of perl.

All the instructions are in the website link.
