Ok, so there were two final issues. First, there were the three JPEG libraries that were not installed on my target system. So I installed them. (I am not sure why the Mezzanine site worked in debug mod even without having those libraries installed, but it works now.) Secondly, SELinux was denying access to httpd to execute those shared libraries, even when they were there. So I used the SELinux diagnostic tools to create SELinux policies to allow that to occur. presto! Everything works now.
ProTip: There are some SELinux denials that are not logged by default! A program that tries to execute a bit of code within a shared library will silently fail if SELinux doesn't approve of that execution. The documentation for RedHat 7 describes how to fix this. (Basically rebuild the selinux policy with an option enabled, and reboot the system. The problem is your logs will fill up quickly and you'll have to sift through some stuff to find the denial. But then you can rebuild the selinux policy without this option enabled to return to normal operation. Once you sift through the denial you can use the normal audit2allow and friends to create the correct policy.) If anyone is curious: I am running this on CentOS 7 with the Software Collections versions of Python 3.5 and Apache 2.4. Lots of custom configuration here. But now it appears to work fully!
