<p>I have found <a href="https://github.com/darrylb123/usbrelay">this on GitHub</a> which has been installed and allows the USB module to be controlled from the command line. Meanwhile, installing <a href="https://metacpan.org/pod/HiPi">HiPi</a> and <a href="https://metacpan.org/pod/RPi::WiringPi">RPi::WiringPi</a> has taken 6 hours so far and is still going...lots of dependencies and some warnings about casting between types that look very C'ish to me...</p>
