Setting Google App Engine SDK on Mac OS X (Tiger)

Google's App Engine SDK requires python 2.5. It can be installed using the community package, MacPorts. If installing from Mac Ports, note that some standard python modules are built separately from the python25, and should be installed as well.

sudo port install python25
sudo port install py25-hashlib
sudo port install py25-socket-ssl
sudo port install python_select

To set python 2.5 as the default version, run:

sudo python_select python25
