Hi,

try this:

apt-get install xserver-xorg-video-ati libs/libgl1-mesa-dri

This one must be missing: libs/libgl1-mesa-dri

Next time you can try to search for the missing file "radeon_dri.so"
here: http://packages.debian.org/

Building an operation system without source code,
is like buying a  self assemble space shuttle without
