I can't seem to get an appliance to build when trying to include packages.  I think this is similar to this

I get a FATAL "Packages not found" though:

I've added the CentOS repositories to my /etc/yum.repos.d/ directory and can install any of those packages using yum from the command line.  My understanding from Marek's earlier post is is that I should not even need to do that...just specify the remote repo URL. 

I apologize if I'm missing something simple here...but I've searched the GoogleMachine and the discussion on this site and tried everything I can think of.  Any help would be appreciated.  If the answer's allready out there, just point me to it.

Thanks,

Ryan
