[Zope] AttributeError: _v_blocks

[Jens Vagelpohl]

mike,

this error usually comes up if the filesystem dtml-pages cannot be read, 
either because they're not found or because the security is set so that 
the user account the zope process runs under is not allowed to read them.

since you're launching as root the user account gets switched to "nobody" 
after binding to port 80, make sure the "nobody" account can at least read 
everything in your zope directory structure (and write to certain files in 
the "var" directory)
