No, it just means that gps isn't on your PATH.

Setting up your PATH on macOS is a whole other question! If you look
into the GPS.app I uploaded (*from the terminal*) you'll see

   $ cat /where/ever/you/put/it/GPS.app/Contents/MacOS/gps
   #!/bin/sh
   export PATH=/usr/local/gnat2017/bin:$PATH
   exec /usr/local/gnat2017/bin/gps

and in order not to have to do the "export" line every time you start a
new Terminal you need to copy that line to the end of one of the startup
scripts, probably ~/.bash_profile_common .

You're welcome.

(a.k.a. "from the command line")

GPS is an IDE (Interactive Develpoment Environment). When it wants to do
a compilation it calls up GNAT's command line tools to do the job.

If you want to compile a file e.g. hello.adb from the command line, then
(assuming your PATH is set up as above!) you say

   $ gnatmake hello.adb
