samba4: bind error #define DLZ_DLOPEN_VERSION 1

4.0.0alpha20-GIT-c69c07e openSUSE 12.1 bind 9.8

Hi. A strange problem with bind not starting after overwriting a git 
from 2 weeks ago. Something like 'should be version 1 not version 2'

It seems to default to the new bind unless we add:
#define BIND_VERSION_9_8    1
to:
source4/dns_server/dlz_minimal.h

to get this bit right:
#ifdef BIND_VERSION_9_8
#define DLZ_DLOPEN_VERSION 1
#else
#define DLZ_DLOPEN_VERSION 2
#endif

Where should I have defined BIND_VERSION_9_8? (I think it's my fault 
since this is an overwrite)

Should we be moving to bind 9.9?
Cheers,
Steve
