I got the Altered RPMs email this morning, and found this thread, then followed the instructions in this post to disable PRELINKING. All that seems to have gone well, but I read later in the thread that it's also recommended that SELinux not be used. I read the man entry for SELinux, and then ran the following command to peak at the configuration file: The file was empty, so I'm assuming that SELinux isn't running on my server. Is that correct? Thanks.
