I used these options on my 14.04 box...
./configure --sysconfdir=/etc/bind \ --localstatedir=/var \ --prefix=/usr \ --with-openssl \ --enable-threads \ --with-libxml2 \ --with-libtool \ --disable-static
... and that fixed the issue described by @dsmarty.

This script doesn't seem to run fine on Ubuntu 16.04 Server, after updating Bind, I get the following errors in syslog:

It seems it uses different paths than standard in ubuntu 16.04 (/usr/var/run vs /var/run). Think if you fix this, you won't need to change the behaviour of apparmor for bind.
Good work btw!
