The first time you grab pygame from svn it will download all the files:

svn co svn://seul.org/svn/pygame/trunk pygame

Ongoing, you simply need to update your local copy occasionally:

svn update

Grab macports packages:

sudo port install sdl-framework
sudo port install sdl_ttf-framework
sudo port install sdl_image-framework
sudo port install sdl_mixer-framework

if the last command is unsuccessful, download and install this:

First, get the following packages:

You will need to modify config_darwin.py to add the default include and library paths for macports.

Before

incdirs = ['/usr/local/include']
libdirs = ['/usr/local/lib']

After

incdirs = ['/usr/local/include','/opt/local/include']
libdirs = ['/usr/local/lib','/opt/local/lib']

python setup.py bdist_mpkg --open

Unpack the tgz

tar xvzf Numeric-24.2.tar.gz
cd Numeric-24.2

In OSX Leopard, you will need to comment out three lines (152-154) in /Packages/RNG/Src/ranf.c

//#if !defined(__sgi)
//      int gettimeofday(struct timeval *, struct timezone *);
//#endif 

Build and install

sudo python setup.py install

Skip this step if you downloaded the pre-built universal binaries for libpng & jpeg

Unpack the tbz

tar xvjf libpng-1.2.16.tar.bz2
cd libpng-1.2.16

Build and install

./configure
make
sudo make install

Unpack the tgz

tar xvzf pygame-1.8.0rc3.tar.gz
cd pygame-1.8.0rc3

Configure

python config.py
