libgtop @2.36.0: Assigning non-zero to $[ is no longer possible at ./lib.pl line 3.

I want to install gnome-system-monitor on my Apple iMac (Late 2015, Intel Core i5), however it is unable to install the dependency package libgtop. The error is pasted below:

$ sudo port install gnome-system-monitor

Testing this on Ventura, I get this error relating to Perl

Making all in lib

It's identical to the several errors in your log file.
