[Mailman-Users] create new list problem

I know nothing about python so if anyone can help explain to me what this means I would be grateful!

I create a new list with the list name, the admin address and password

[root@www bin]# ./newlist myList admin@mysite.com password

Traceback (innermost last): File "./newlist", line 39, in ? from Mailman import MailList File "/home/mailman/Mailman/MailList.py", line 39, in ? from Mailman.ListAdmin import ListAdmin File "/home/mailman/Mailman/ListAdmin.py", line 33, in ? from Mailman import Message File "/home/mailman/Mailman/Message.py", line 30, in ? import sha ImportError: No module named sha

Cheers,

Cary.
