Rowland I seem to have solved all of my Bind related issues on 12.04.

To summarize my main issues were

  * Required upstart script to create /var/run/named temp directory.
  * Ignore error configuring command channel from '/etc/bind/rndc.key'
    couldn't add command channel 127.0.0.1#953: file not found
  * Issue /usr/local/samba/sbin/samba_upgradedns --dns-backend=BIND9_DLZ
    so it appears in /usr/local/samba/private
  * Update to Samba 4.3 to resolve `SAMBA_4.3.0' not found (required by
    /usr/local/samba/lib/ldb/dns_notify. so)
  * Update to Samba 4.3 to resolve `SAMBA_4.3.0' not found (required by
    /usr/local/samba/lib/l db/tombstone_reanimate.so)

I didn't seem to have any issues during the actual compile. Here is my 
system info to compare to yours. Thanks for everyone's help.
