[Observium] Links not working

Hello,

I just installed Observium from SVN on Ubuntu Ubuntu 10.04.4 LTS. I fallowed the Ubuntu installation guide. Observium comes up but when I log in. But when I click any of the links at the top they say "Not found" and give a invalid URL. For example when I click Devices> Add Devices it sends me to server.com/addhost/ which doesn't exist, because in the addhost directory is in a subdirectory called "pages." Did I miss something during the install? I have tried it a couple times, and reinstalled the server.

Thanks!
