Those are to be done in chroot.

become root, then chroot.  Use su.

If the problem persists, you are going to have to retrace your command  
history with the book and find out where a mistake was made.
I encountered this problem one time when buliding CLFS and testing  
git, and I couldn't figure it out, restarted from scratch and all was  

Maybe you'll find out why.
