How about the latest Evolution (2.21)?
I have no idea how to do it myself

pidgin-plugins-pack and piding-otr would be nice to see in the list

Are the improvements in mesa that you made in the current release of mesa?
If not Where can I get the source for mesa so I can compile and install it in debian 4.0?
I would assume that I would download mesa from here
http://www.mesa3d.org/

Are the improvements in xserver-xorg-video-ati that you made in the current release?
Would I download the source for xserver-xorg-video-ati at the mirrors listed at here
http://www.x.org/wiki/Releases/Download?action=show&redirect=Mirrors

Is xf86-video-ati-X11R7.2-6.6.3.tar.gz the same thing as xserver-xorg-video-ati
