Back to Building.

Build steps for debian (and debian derivatives like Ubuntu):

sudo apt-get install fossil
sudo apt-get install tk8.5-dev
sudo apt-get install freeglut3-dev
fossil clone http://www.etoyoc.com/fossil/canvas3d canvas3d.fos
mkdir canvas3d
cd canvas3d
fossil open ../canvas3d.fos
sh configure --with-tcl=/usr/share/tcltk/tcl8.5 --with-tk=/usr/share/tcltk/tk8.5
make
wish8.5 ../canvas3d/demo/triangles.tcl
# Install
sudo make install

Note: on older systems freeglut3-dev was glutg3-dev
