If you hadn't said "new install", my suspicion would have been that 
you've upgraded to this version of Cobbler from a version before 1.0, 
before the mod_python infrastructure was introduced, and therefore have 
a "cobbler.conf.rpmnew" file hanging around in your Apache 
/etc/httpd/conf.d directory. If that was the case, I would have said 
copy this file over the non ".rpmnew" one and restart httpd.

I assume you are installing with the latest RPM from EPEL 5 testing? The 
latest is 1.2.4. Maybe you installed with --noscripts or something else 
weird?
