[Zope] <dtml-whois> tag don't work

[Marcello Lupo]

Hi, i tried ti install whoistools on my zope 2.3.0 but i found
an error in the source of whois.py at the sock.connect line which was 
sock.connect(server, port) i correct it with sock.connect((server,
port))
and it started ti run in python.
But wher i try to use it from the <dtml-whois> tag i gat everytime :

Unexpected tag, for tag <dtml-whois "'internic.net'">, on line 1 of ppp 

I see that the Zope don't list the prodects in the control panel under
Products.
Any ideaa??
thanks,
Bye,
Marcello
