smb-double-pulsar-backdoor.nse

I'm having issues with this script I downloaded & ran today (
https://svn.nmap.org/nmap/scripts/smb-double-pulsar-backdoor.nse).
When I first ran it, it failed on all the hosts. Then I ran it with -d
(debug) switch. Here's what I'm seeing with every host in the result file:

"NSE: smb-double-pulsar-backdoor against 10.11.1.74 threw an error!

...bin/../share/nmap/scripts/smb-double-pulsar-backdoor.nse:61: attempt to
call field 'pack' (a nil value)

stack traceback:

    ...bin/../share/nmap/scripts/smb-double-pulsar-backdoor.nse:61: in
function 'send_transaction2'

    ...bin/../share/nmap/scripts/smb-double-pulsar-backdoor.nse:130: in
function <...bin/../share/nmap/scripts/smb-double-pulsar-backdoor.nse:93>

(...tail calls...)"


Any ideas why this is happening?


Thanks,

Alex
