[CalendarServer-users] Zope Error on run

[Brendan Chard]

I am running into an issue when trying to run Calendar Server for the  
first time.

I ran ./run -s without issue and the setup script was able to download  
and install the require modules.

However, after completing the steps in the README when I run ./run to  
start the server I get the following output.

I am on a RHEL 4 box that has cPanel.  I have installed my own copy of  
Python 2.6 at /opt/python.  Python 2.4 is installed with cPanel and I  
did not want to overwrite that.

Thanks for your help.
