Softether compile error using debian-8.5-console-armhf-2016-06-05-2gb

Trying to compile Softether VPN using BBB Rev B board in Jesse console as noted in subject line. Get the following output in Terminal:

./.install.sh: 81: ./.install.sh: make: not found
root@beaglebone:/vpnserver#

Not sure what to do next. Following youtube video where install was in Pi Raspian Jesse running in console mode using the same download from the Softether site.

Files downloaded and extracted from Softether site are below.

Thoughts?

So... Install make?

sudo apt-get update
sudo apt-get install build-essential

Thank you Robert - exactly the help I needed as a new user of Debian on the BBB. I only have limited experience with full installs of Ubuntu 16.04 and earlier on my home computer where all utilities are available without having to know much of the internal workings of Linux.

Regards,
