[Zope3-dev] Error doing "Chapter 13, Writing a new Content Object" of the zope 3 book.

[Pupeno]

Hello,
I am starting with Zope 3, so far I like it :)
But going thru the Chapter 3 of the Zope 3 book, I've got an error and I don't 
know how to solve it (note, I am running Zope 3.1.0b1).
Here's the whole errror:

pupeno at lab ~/zope/bin $ ./runzope

pupeno at lab ~/zope/bin $

I've commented out
<require permission="zope.ManageContent" 
interface=".interfaces.IMessageContainer" />
and Zope started, but I do not have the option to add a message board.
Does anybody know what am I doing wrong ?
Thank you.
