LFSMake ReStart

Hi;
After crashing LFSMake and Mandrake had to start
over from scratch. Made it through "make dive" with
minimal problems. Ran "make stage2" with the
following result:

Fixing file/directory ownership and permissions...
chown: root.root: invalid user
make: *** [/usr/installinfo/MAKEDEV-2.5] Error 1

Why an "invalid user" and how is it to be corrected?
