How do you do package management on MacPorts for languages which might
need modules which MacPorts doesn't have?
This problem exists for many languages supported by MacPorts; ie:
Perl, Python, Raku, Julia, etc
The answer is different for each language. For Python, standard
procedure is to use venv. <https://docs.python.org/3/library/venv.html>
I would assume for perl that if there isn't an equivalent mechanism,
cpan should at least have an option to choose a different installation
prefix. I don't know what the situation is for Raku and Julia.
