you need to install python.

The best way is to use MacPorts. Download and install MacPorts, then install Python via MacPorts by typing the following commands in the Terminal:

sudo port install python26 python_select
sudo python_select python26

i figured it out myself.

i changed in each Three20 project the line in: "build phases > lint > shell" to: /usr/bin/env /opt/local/bin/python2.6 ../scripts/lint
