Description of problem:

Install mod_auth_cas breaks httpd.  Appears to be looking for some SSL symbols that aren't there or aren't loaded.

mod_auth_cas requires doesn't include any SSL things, but I do have mod_ssl and openssl packages installed.

Easily fixed by removing mod_auth_cas package

Version-Release number of selected component (if applicable):
mod_auth_cas.x86_64 0:1.0.8.1-2.el6
redhat-release-server-6Server-6.1.0.2.el6.x86_64
epel-release-6-5.noarch
httpd-2.2.15-9.el6.x86_64
mod_ssl-2.2.15-9.el6.x86_64

How reproducible:
Very

Steps to Reproduce:
1. yum -y install mod_auth_cas
2. service httpd restart
  
Actual results:
