-2) Uninstall all openscenegraph packages through Synaptic if they are
installed. Version 1.1 needs to be totally gone.

-1) Still in Synaptic, make sure you have all the repositories necessary
to get OSG and its dependencies. Click Settings -> Repositories. In the
"Ubuntu 6.10" tab make sure all 5 top checkboxes are checked in. Close
the dialog.

0) Do either of the following: click the Reload button in Synaptic, or
close Synaptic and from the terminal run "sudo apt-get update".

1) Install all the dependencies for building OSG using Ubuntu's package
system. On a terminal, enter the command "sudo apt-get build-dep openscenegraph"

2) Follow the OSG compilation directions in the Morefield/Malloy tutorial:
   http://www.cs.clemson.edu/~malloy/courses/3dgames-2007/tutor/index.html

3) In the tutorial, each time it says to do "sudo make install" instead
do "sudo make INST_LOCATION=/usr install". This will make sure it puts
things in the usual place for Ubuntu.

4) Once it's all compiled you should be able to compile the OSG tutorial
test program.
