I've liked this song too ever since hearing it on the Louisiana Gumbo Putumayo compilation. The guitar in the recording doesn't seem to be playing chords per se, but playing Gm and Cm a half bar each seems to fit just fine. Most of the song lies in getting the rhythm right.
Then the main guitar riff is something like:
E ---------------------------------------------
B ---------------------------------------------
G ---3-------------3--------------------------
D 5--------3----5--------3-4-5--------------
A ------5-------------5-----------------------
E ---------------------------------------------
Hope that helps! I'm planning on playing this at a Halloween party tomorrow!
