Install iperl - no error messages; but it seems not be installed

I tried to install wiper using this link:

https://github.com/EntropyOrg/p5-Devel-IPerl](https://github.com/EntropyOrg/p5-Devel-IPerl

I got several install complete messages and no error messages. These failed:

iperl console
iperl notebook

I got “command not found”. I assumed this was a path issue. My $PATH is:
/Applications/anaconda2/bin:
/Applications/anaconda2/condabin:
/Library/Frameworks/Python.framework/Versions/3.8/bin:
/opt/local/bin:
/opt/local/sbin:
/usr/local/bin:
/usr/bin:
/bin:
/usr/sbin:
/sbin:
/opt/X11/bin:
/Users/JRW/scripts:
/usr/local/mysql

This is the correct setting for jupyter itself. But
sudo find / -type f -name iperl -print
did not find anything. I am confused by the fact that I got so many “install complete” messages, but not iperl (apparently). Can somebody give e me some guidance?
