Just in case you missed it and were having the same problems as I, the latest edge build appears to fix problems with urchin5. Use the 'x' theme and everything works great.
I posted on cpanelthemes a fix to get it working under xcontroller, hopefully he will release a fixed version soon.
The fix is creating two symbolic links and creating a new file, and also involves editing a few pages to point to urchin.cgi as opposed to urchin.html (at least I had to do this!)
I know some people say they didn't have problems with urchin5, but for those who did this is good news
how to fix xcontroller for urchin5
(BTW doing that should not break urchin4, if you're worried)
