I’ve installed it with cpanminus, which in turn can easily be installed via Homebrew.
Unfortunately it's only returning 4 of 5 rows (skipping the first row after the header-line), and I have no idea why. (I did have to change the line-endings of the file to Unix […]
It seems you have a different file?! Hans’s file from the download link above does have exactly 4 rows (rows 0 to 3, plus one header row).

2-modus 2-Betrieb
4-modus 4-Betrieb
afdekkap Abdeck, ,kappe
afdekking Abdeckung
In my file the first row (after the header row) is the one with “2-modus” and “2-Betrieb”.
(The commas have been added by me to the source CSV, for testing ("Abdeck, ,kappe").)
And when I add a fifth row, the script returns exactly 5 rows. The same for 6 rows and so on. It also works with Hans’ original CRLF line endings.
Can it be that your Macports install gave you an outdated module, once again
