Jakub Gemrot created a nice 9 steps tutorial covering the setting up of Pogamut 3 with Maven. You can download the tutorial here.

EDIT: Tutorial was updated on 28.10.2011 (Step 7 is not optional anymore, the paths in step 7 were corrected)

Note that the latest Pogamut 3 stable release is 3.2.4.

Best,
The Pogamut team
