samba_dnsupdate and samba_spnupdate scripts fail

[Anatoliy Atanasov]

Hi Jelmer, Tridge,

The scripts for samba_dnsupdate and samba_spnupdate fail with this error, when i run samba with sudo:
sudo bin/samba -i -M single -d3

Calling DNS name update script
Calling SPN name update script
/home/ant/bin/rwdc/sbin/samba_dnsupdate: Traceback (most recent call last):

I deleted everything from the installed prefix, did make install and samba-tool vampire after that.
My python path is: PYTHONPATH=:/home/ant/bin/rwdc/lib/python2.6/site-packages/
But for a root user the PYTHONPATH is not set. I installed samba with sudo and with root user the result was the same. When i added the PYTHONPATH to the environment the error was resolved. Where is the place to do that in the code?
