There are security updates upstream for CentOS (4 and 5) 
and it looks like the CentOS 5 ones have been rebuilt 
and rolled out. How come the CentOS 4 branch lags behind, 
or are the CentOS 5 devs different from the CentOS 4 devs? 
If more volunteers are needed I'm sure assistance could 
be offered by the CentOS community.
