Need help with PHP web app bootstrapping error potentially related to Zend-Collection of common programming errors

I am trying to get a program called OpenFISMA running on an Ubuntu AMI in AWS. The app is not really coded on the Ubuntu platform, but I am in my comfort zone there, and have tried both CentOS and OpenSUSE (both are sort of “native” for the app) for getting it working with the same or worse results. So, why not just get it working on Ubuntu? Anyway, the app is found here: www.openfisma.org and an install guide is found here: https://openfisma.atlassian.net/wiki/display/030100/Installation+Guide The install guide kind of sucks. It doesn’t list dependencies in any coherent way or provide much of any detail (does not even mention Zend once on the entire page) so I’ve done a lot of work to divine the information I do have. This page provided some dependency inf (though again, Zend is not mentioned once): https://openfisma.atlassian.net/wiki/display/PUBLIC/RPM+Management#RPMManagement-BasicOverviewofRPMPackages

Anyway, I got all the way through the install (so far as I could reconstruct it). I am going to the login page for the first time, and there should be some sort of bootstrapping occurring when I load the page. (I am not a programmer so I have no idea what it is doing there.) Anyway, I get a message on the web page that says: “An exception occurred while bootstrapping the application.”

So, then I go look in /var/www/data/logs/php.log and find this message:

[22-Oct-2013 17:29:18 UTC] PHP Fatal error:  Uncaught exception 'Zend_Exception' with message 'No entry is registered for key 'Zend_Log'' in /var/www/library/Zend/Registry.php:147
Stack trace:
#0 /var/www/public/index.php(188): Zend_Registry::get('Zend_Log')
#1 {main}
  thrown in /var/www/library/Zend/Registry.php on line 147

This occurs every time I load the page. I gather there is an issue related to registering the Zend_Log variable in the Zend registry, but other than that I really have no idea what to do about it. Am I missing a package that it needs, or is this app not coded to register the variables properly? I have no clue. Any help is greatly appreciated. The application file referenced in the log message (index.php) is included below.
