Just as a reference if anyone else comes across this issue. If you follow the tutorial exactly as it states regarding the Bind setup then you will receive the stated error.
To resolve the issue I ignored the error and continued with the installation. Once ISPConfig completed its installation it also reported that it was unable to start NAMED. I continued and add a website and the DNS for the new website.
Once the DNS entries were created, ISPConfig corrected the issue itself by modify the contents of the named.local file to the correct values.
It seems the issue lies with the default named.local file that is provided when installing BIND. Hope this helps someone.
