I am running a CentOS 5 based virtual machine in the AWS cloud. I am using epel and remi and get some crazy broken dependencies when I try to update php.

I have searched around and have not been able to find a solution for what is happening. Here is my output:

# yum --enablerepo remi update php

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

I'm trying to figure out if these dependency problems are caused by AWS not having the default CentOS repositories enabled (they use their own repo as the base repo).
