Hi!
I set up a Debian Archive Server for Panda3D. If you want to install Panda3D, just put the line
deb http://www.bios.kicks-ass.org/debian/ sarge/
into your /etc/apt/sources.list using either an editor of your choice or enter the URL when being asked with apt-setup
Now you can install/search Panda3D with Apt like you would with any other program.
In case you want to test the current beta build (named Panda3D 1.1), use the following line:
deb http://www.bios.kicks-ass.org/debian/ testing/
Have FUN!
