I know this howto is written for etch (stable), but I recommend using these binary packages from sid (unstable) - a lot less work... If you also install daemontools-run, you get more control over daemontools.

Assuming you have installed all these packages (from sid), the "Next we configure dnscache, axfrdns, and tinydns" step becomes

dnscache-conf dnscache dnslog /etc/dnscache
axfrdns-conf axfrdns dnslog /etc/axfrdns /etc/tinydns 192.168.0.100
tinydns-conf tinydns dnslog /etc/tinydns 192.168.0.100

followed by 

update-service --add /etc/dnscache
update-service --add /etc/axfrdns
update-service --add /etc/tinydns

You don't maintain the symlinks manually anymore, and you can use update-service to remove the service to.
