You can fix this by completing what Homebrew should have done, but for some reason is not.
Homebrew is not creating the symlinks needed for BIND related executables. Typically this happens automatically as part of the installation process.
If you navigate to your homebrew "Cellar", find the bind installation and the sbin directory within it, you will find all the named executables needed... for example, my sbin directory for bind is located at:
/usr/local/Cellar/bind/9.9.3-P2/sbin
So the goal would be getting these files on the executable path. The method is up to you.
You can do as Homebrew should and create a symlink for each of the files found in bind/*/sbin. These symlinks are created in /usr/local/bin.
for example:
ln -s /usr/local/Cellar/bind/9.9.3-P2/sbin/named /usr/local/bin/named
The other option is to put the homebrew bind path on your executable path by adding it to your .bashrc, .zshrc, .profile or whatever you use.
Personally I opted for following the convention homebrew uses and created individual links in my /usr/local/bin directory.
Once you have gone through all of this you should be able to configure things using rndc-confgen, etc. as directed by a number of tutorials.
