Description of problem:
When trying to create a new cluster from the Luci server, an error stating "global name 'os' is not defined".  Note: The system is actually running Scientific Linux Cern which is built off of RHE4.6, the versions of Luci/Ricci used are those released by Red Hat.  

Version-Release number of selected component (if applicable):
Name   : luci
Arch   : x86_64
Version: 0.11.1
Release: 5.el4
Size   : 164 M
Repo   : installed
Summary: Remote Management System - Management Station

How reproducible:
After installing Luci and changing the iptables to enable the ports defined by the Conga documentation for 4.6; start up the luci server (/sbin/service luci start) and setup an administrator password (luci_admin init).  In a web-browser go to the page listed by the luci server.  Click on the cluster tab and then the create new cluster.  Type in a cluster name, and the name of at least 1 server to be added, then submit.  The cluster is not created instead a 'Site Error' occurs, stopping the operation. The error details are:
Error Type: Name Error
Error Value: global name 'os' is not defined
Error Date: <current date and time>

Steps to Reproduce:
1.Start a new luci server, in a web browser go to the site listed (server.domain:8084).
2.Login, click on the 'cluster' tab, click on 'create a new cluster' 
3.Enter a name for the cluster along with at least one valid node name & password, then click submit.
  
Actual results:
A 'Site error' occurs, stopping the operation. Error details are:
Error Type: Name Error
Error Value: global name 'os' is not defined
Error Date: <current date and time>

Expected results:
The cluster is created.

Additional info:
The bug seems to be browser independent (occurs on IE7,FireFox3,Konquerer). I recognize the error text from python, possibly a script forgot to 'import os'?
