We've been dealing with this for years as well trying to build el4 
packages on el5 hosts.  The issue (in our case) seems to be related to 
the udev package being installed and the %postinstall script running 
/sbin/udevstart.  The process never exits correctly and the first 
attempt to build fails.  After the root cache is created the next build 
works great.
