Tentando instalar o pygame através do easy_install no Ubuntu 12.10 e os erros que isso me dá:

Essa resposta do SO fornece o symlink correto. Você precisa remover o /usr/include/linux/videodev.h que você criou - ele está vinculando à versão errada do arquivo de cabeçalho.

sudo apt-get install libv4l-dev
cd /usr/include/linux
sudo ln -s ../libv4l1-videodev.h videodev.h

Pygame precisa de algumas dependências:

sudo apt-get install python-dev libsdl-image1.2-dev libsdl-mixer1.2-dev libsdl-ttf2.0-dev   libsdl1.2-dev libsmpeg-dev python-numpy subversion libportmidi-dev ffmpeg libswscale-dev libavformat-dev libavcodec-dev

Se você não quiser instalá-los, instale o pacote pré-compilado:

sudo apt-get install python-pygame

É a versão do pygame nos repositórios ( python-pygame )  velho demais? Se não, você deve tentar instalá-lo primeiro.

Caso contrário, use python-pip para instalar o pygame :

sudo pip install pygame

Por que usar pip sobre easy_install?
