[Zope] - beta 3 won't install

I've tried everything and cannot get b3 to install. I'm on a slackware box, beta 2 installed fine. error message is: Installation Failed! you must have administation privledges to successfully run this installation. I have tried every combonation of permissions to get through this with no luck. I get the same error even when trying to install as root. I am installing into the same directory level as I installed beta 2 into, the dir have the same permissions and were created in the same way by the same user. Any tips? DAve.
