[TYPO3] typo3 4 installation problems

[rocky]

Hey Group,

I tried to install typo3 4 on my Debian sid box. I finished the 
installation process but I got the following error when going to back end

Plus I could not log in to the backend with username admin and password 
password. Do they changed in typo3 4?

I would really appreciate it, if any of you could give me some hint or 
some URL references regarding to typo3 4 installation on Debian sid?
