Pgfutter command not found error in Ubuntu bash

[AlexGhanem]

I cannot seem to get pgfutter to run at all in my Ubuntu terminal. I keep getting:
pgfutter: command not found error

running ./pgfutter gives me the help options but the application itself wont run no matter how many chmod build attempts I try.

Same here with MacOs 11.5.2.
