If you're not using match-making or Glide-In, Condor-G doesn't need a  
Collector or Negotiator. It doesn't hurt anything to run them, but if  
you prefer not to, just comment out the line that sets CONDOR_HOST in  
your config file and the errors should go away.

It seems likely you've got some developer confusion going on. (Sorry,  
couldn't resist :-)

Condor-G does not need to be run as root. If you start Condor as an  
ordinary user, you should be able to ignore any messages about the  
passwd_cache. What are the messages you're seeing, by the way?
