[Zope-PTK] I get an I/O error when creating a PTK Portal

[me]

Has anyone experienced this?  After installing Zope 2.2.0 (binary
release) and ZopePTK-0.8.2-complete, I get an I/O error when I try to
create a portal.

I can see the portal in the folder I created it in (the root folder) but
I get the same I/O error when I try to access it.

Here's the error...

Zope Error

Zope has encountered an error while publishing this resource.
