SnortWatch. Any docs with detailed installation?

[NismoSkyline <NismoSkyline () comcast net>]

Trying to get this running. This is the tool that has email capabilities correct?  Is there any special libraries 
required in order for it to run? 
Did a:
[root@ninja snortwatch-0.7]# ./snortwatch.py
Traceback (most recent call last):
  File "./snortwatch.py", line 21, in ?
    import gtk, GDK, libglade
ImportError: No module named gtk

Also, is there any documentation anywhere on this?
TIA
