would it help if I add 'no integer;' ad the beginning of the program?

My problem is I don't actually own a M1 or M2 Mac myself (to be precise I don't own any Mac at all), this problem got reported to me by a user who runs my program on a M1 Mac, and he is the one who tests the code I give him and then reports back the output he gets.
Now that after some back and forth I finally managed to narrow down the issue to those lines of code posted in the first post I'd prefer not to bother him again straight-away with more questions and tests, I don't want to strain his willingness to help too much.

That's why I was hoping that someone here with a M1/M2 Mac and good Perl knowledge could look into this a bit.

If it helps, these are the instructions my user followed to install MacPorts Perl on his M1 MacBook:
