I installed a framework version, using otherwise default settings, and it
played nicely with my existing Python installation:

./configure --enable-framework
make
sudo make install

On one machine this worked without any issues.  On another, I had to fix the
symbolic link at /Library/Frameworks/Python.framework/Versions/Current to
point to the [...]/Versions/2.6 directory, rather than the
[...]/Versions/3.0 directory that the installation seemed to have linked to.
The executables live in /usr/local/bin/ and will probably be in your default
$PATH, so just issuing

python3.0

At the command line should put you into the new interpreter.
