[Zope] Importing A Plone Instance

[Tom Purl]

I was developing a Plone site this afternoon and exported it to a file, 
Plone.zexp.  I then moved that file to the following directory on my 
Debian Linux box:

/var/lib/zope/import

I then go to import the Plone instance by entering Plone.zexp in the 
"Import file name" textbox and click on the "Import" button.  However, 
when I do, I get the following error:

Error Type: IOError
Error Value: [Errno 13] Permission denied: 
'/var/lib/zope/instance/default/import/Plone.zexp'

I thought that there might be a problem with permissions because the 
import folder's owner is root and its group is root.  However, *every* 
file in directory associated with Zope shares this trait, and I haven't 
seen any other problems elsewhere.  Also, I'm logged in as a user that 
has Manager and Owner rights over the root folder of my Zope instance.

I googled for some help but couldn't find anything.  Has anyone else 
seen a problem like this?

Thanks in advance for any help!
