From Apache's [cgi] docs (22/2/2017) ...
"... When a program runs through the web server as a CGI program, it may not have the same PATH. Any programs that you invoke in your CGI program ... will need to be specified by a full path, so that the shell can find them when it attempts to execute your CGI program. ..."
