Unfortunately, BIND's logging is verbose but not useful.

No clue.

Other than a minor typo (should be args[0] instead of args[1]), the update 
example works for me, assuming the server is properly configured with the 
zone and TSIG key in the program.

I'm not sure what's confusing about the update program.  It has pretty 
complete help for all of the commands, and the usage to add a single 
record would be something like:

> server <ip address of server>
> zone <zone name>

or, as an example:

> server 127.0.0.1

If you fix the one character typo in the example, it is working code.
