man chroot: 
If no command is given, run ??${SHELL} -i?? (default: /bin/sh).

Likely bash relies on some library that is not available. (this is an 
error thrown by bash, not by chroot!)
I don't see why you think running chroot is a good idea when the website 
says to do something else.

Apart from that I very much doubt that using an article from 2003 based on 
FreedBSD 4.x is really what you want to follow. There is some good config 
stuff in there, but chrooting regularly updated daemons doesn't appear to 
be a good idea to me. You have to recompile them again and again for each 
security bug found. If you don't do this immediately you may actually be 
in more danger than without it. If you want to go that route, why then use 
an rpm-based system at all? Rather use OpenBSD.
There may be good reasons why you do like you do, but in general I would 
rather use what's coming with the system, like SELinux, an IDS system and 
other monitoring, tight firewall rules and tight access control.
