You need a later version, this is what I used to do:

apt-get -y remove bind9 &> /dev/null # <-- this was only installed to 
get all the required configuration files!
wget ftp://ftp.isc.org/isc/bind9/9.9.2-P2/bind-9.9.2-P2.tar.gz
tar zxf bind-9.9.2-P2.tar.gz
cd bind-9.9.2-P2
./configure --prefix=/usr --mandir=/usr/share/man 
--infodir=/usr/share/info --sysconfdir=/etc/bind --localstatedir=/var 
--enable-threads --enable-largefile --with-libtool --enable-shared 
--enable-static --with-openssl=/usr --with-gssapi=/usr  
--with-dlopen=yes --with-gnu-ld --enable-ipv6 
CFLAGS='-fno-strict-aliasing -DDIG_SIGCHASE -O2' 
LDFLAGS='-Wl,-Bsymbolic-functions -Wl,-z,relro' 
make install

NOTE: this was some time ago, there are newer versions available, if you 
do go with a newer version and it throws an error about dlopen, just 
remove '--with-dlopen=yes'
