Pygame is a cross-platfrom library designed to make it easy to write multimedia software, such as games, in Python. Pygame requires the Python language and SDL multimedia library. It can also make use of several other popular libraries.
You should definitely begin by installing a binary package for your system. The binary packages usually come with or give the information needed for dependencies. Choose an appropriate installer for your system and version of python from the pygame downloads page. http://www.pygame.org/download.shtml
Installing from source is fairly automated. The most work will involve compiling and installing all the pygame dependencies. Once that is done run the "setup.py" script which will attempt to auto-configure, build, and install pygame.
Much more information about installing and compiling is available in the install.html file.
If you are just getting started with pygame, you should be able to get started fairly quickly. Pygame comes with many tutorials and introductions. There is also full reference documentation for the entire library. Browse the documentation from the documenantation index. docs/index.html.
On the pygame website, there is also an online copy of this documentation. You should know that the online documentation stays up to date with the development version of pygame in hg. This may be a bit newer than the version of pygame you are using.
Best of all the examples directory has many playable small programs which can get started playing with the code right away.

There's many more folks out there who've submitted helpful ideas, kept this project going, and basically made my life easer, Thanks!
Many thank you's for people making documentation comments, and adding to the pygame.org wiki.
Also many thanks for people creating games and putting them on the pygame.org website for others to learn from and enjoy.
Lots of thanks to James Paige for hosting the pygame bugzilla.
Also a big thanks to Roger Dingledine and the crew at SEUL.ORG for our excellent hosting.
Pygame is obviously strongly dependent on SDL and Python. It also links to and embeds several other smaller libraries. The font module relies on SDL_tff, which is dependent on freetype. The mixer (and mixer.music) modules depend on SDL_mixer. The image module depends on SDL_image, which also can use libjpeg and libpng. The transform module has an embedded version of SDL_rotozoom for its own rotozoom function. The surfarray module requires the python Numeric package for its multidimensional numeric arrays.

This basically means you can use pygame in any project you want, but if you make any changes or additions to pygame itself, those must be released with a compatible license. (preferably submitted back to the pygame project). Closed source and commercial games are fine.
The programs in the "examples" subdirectory are in the public domain.
