However, if you decide to build it from source that is pretty easy too:
$ sudo apt-get install scons python-pygame
Download the cgkit source file from its Sourceforge page and unzip it.
Building the code is a two-step process: first the C++ library using scons and then the Python wrappers and installing them:
$ cd supportlib $ scons $ cd .. $ sudo python setup.py install
Tried with: cgkit 2.0.0 and Ubuntu 12.04 LTS
