CentOS 6 Yum Update – Packages Skipped Due to Dependency Problems

I'm trying to keep my offsite backup server up to date so I've run an update and I'm getting dependency issues. I haven't got a clue how to continue. Below is the output from from YUM.

[root@localhost philosophy-admin]# yum update --skip-broken
