Arduino 1.5.2 command line build

Hi,

I'm trying to use the command line build feature available since arduino 1.5.2, with no success so far. I'm trying with the instructions provided in this page: Arduino IDE 1.5 from command line · arduino/Arduino Wiki · GitHub, but the 'arduino' command is not recognised from the command line. Probably I'm missing something in my $PATH, but I'm out of ideas. I'm using Mac OS X 10.8.4.

Does anyone know how to make it work?

Thanks in advance!

What OS?
