First run this to install dependencies:
sudo apt-get install mercurial python3-dev python3-numpy
libsdl-image1.2-dev libsdl-mixer1.2-dev libsdl-ttf2.0-dev libsmpeg-dev
libsdl1.2-dev libportmidi-dev libswscale-dev libavformat-dev libavcodec-dev libfreetype6-dev
Then download the source for pygame:
First install mercurial if you dont have it installed:
sudo apt-get install mercurial
then:
hg clone https://bitbucket.org/pygame/pygame
Now build and install pygame for Python 3.4:
cd pygame
python3 setup.py build
sudo python3 setup.py install
Additional comments:
The only version of Python3 I had installed was 3.4 if you have other versions
you might have to be more specific.
