The package is broken for most people because it uses /bin/bash in its pre/post install/remove scripts, and the N900 only has /bin/sh by default. As a workaround, you can 'apt-get install bash' from a root shell, then the packages will install/uninstall correctly.

Unfortunately, you then find that because its only a basic port, many game screens are too tall to fit on the screen with the title bar, and you can't put it in full screen. Needs more work...
