[ubuntu] Nagios nsti plugin

Hey guys I have followed this tutorial:
http://linuxdrops.com/step-by-step-i...uide-for-nsti/

I have nagios up and running using Ubuntu 11.10.

I have done everything what the tutorial told me to do but I cannot open [localhost]/nsti/. When starting ./install.py I get some errors mabye those are related to my problem?
