Error with manual install on Debian 8

Installing manually on Debian 8 running in a EC2 instance on AWS. I have followed these:
instructions to the T, and going through with everything going swimmingly until the very last step (/usr/src/freepbx/install -n) fails with the following message:
PHP Warning: simplexml_load_file(): I/O warning : failed to load external entity “module.xml” in /usr/src/freepbx/install on line 14
PHP Notice: Trying to get property of non-object in /usr/src/freepbx/install on line 16
Assuming you are Database Root
Checking if SELinux is enabled…Its not (good)!
PHP Warning: require_once(installlib/installer.class.php): failed to open stream: No such file or directory in /usr/src/freepbx/installlib/installcommand.class.php on line 211
PHP Fatal error: require_once(): Failed opening required ‘installlib/installer.class.php’ (include_path=’.:/usr/share/php:/usr/share/pear’) in /usr/src/freepbx/installlib/installcommand.class.php on line 211

What the heck am I doing wrong?
