I am trying the example code for drawing the graphs on my machine. Here is the error I am getting. I am sure this is something to do with the installed packages. I am using Debian and am not sure what package or path is missing.

You need the libgv-python package. I should have made this a dependency...

Unfortunately there is a currently a bug in the Debian package for libgv-python. They put part of the python binding in the wrong place. In order to fix this, you have to run the following command as root:

ln -sf /usr/lib/pyshared/python2.5/libgv_python25.so /usr/lib/pymodules/python2.5/_gv.so
