Failing to install Doom
 

I tried to install Doom on my brand new 770 (OS 2006) but after downloading the package from http://marceloeduardo.com/apt I got an error message about a package dependancy. Ok, I downloaded maemo-games-startup but this one doesn't install, I got an error message like package not compatible (sorry, the error msg is in German).

Hm, probably I'm doing something stupid...
:)
Any guess?
