I take it you've never compiled anything yourself before, so I'll go through
it step by step. The bzip and gzip are just two different compression
methods, so it doesn't matter which tarball you download. In order to go
further, you'll need to register at developer.apple.com and download Xcode.
You won't need to use Xcode itself, but you need the compilers that come
with it. It's a pretty big download, so this will take a while.
Once you install Xcode, open up a terminal
(/Applications/Utilities/Terminal.app) and cd (change directory) to wherever
you put the extracted tarball. In that directory, run the configure file.
Since your on OS X, you probably want a framework build (installed to
/Library/Frameworks) instead of a normal build, which installs to
/usr/local. To do this, execute the command "./configure
--enable-framework". If you want to look up the other options, run
You'll probably get an error about missing dependencies. The easiest place
to find these is in a package manager such as fink (www.finkproject.org) or
macports (www.macports.org). Fink is easier and faster, but macports is
usually more up-to-date and flexible since it compiles everything locally.
Both of them will work. Just don't forget to add the paths (macports is in
/opt/local/ and fink is in /sw/)
Once the configure command works successfully, run the commands "make" and
"sudo make install". The first one will compile everything, the second will
put it where it's supposed to be. After running the latter, you'll be
prompted to enter your password. That should install it to
/Library/Frameworks/Python.framework/versions/3.1. I haven't installed 3.1
myself but assuming it does the same thing as 3.0, it should a python3.1
executable (symlink actually) to /usr/local/bin so you shouldn't need to add
anything to the path.
