Installation on Debian Etch

hi, i got a problem when i run screenlets by console, on graphic mode nothing happen but the problem never run, but the console show me the follow things:

<Begins here>

osval@lisa:~/Desktop/screenlets$ screenlets
Gtk-Message: Failed to load module "atk-bridge": libatk-bridge.so: no se puede abrir el fichero del objeto compartido: No existe el fichero o el directorio
GTK Accessibility Module initialized
No module RSVG , graphics will not be so good
Traceback (most recent call last):
  File "/usr/share/screenlets-manager/screenlets-manager.py", line 28, in ?
    import screenlets
  File "/usr/lib/python2.4/site-packages/screenlets/__init__.py", line 51, in ?
    from options import *
  File "/usr/lib/python2.4/site-packages/screenlets/options.py", line 30, in ?
    import utils
  File "/usr/lib/python2.4/site-packages/screenlets/utils.py", line 16, in ?
    import dbus
ImportError: No module named dbus
osval@lisa:~/Desktop/screenlets$

<...and ends here>

where system says: "no se puede abrir el fichero del objeto compartido: No existe el fichero o el directorio"
it mean this : "Can't open the file of shared object: Doesn't exists the file or directory"

i hope that you guys can help me.. thanks for you help, a friend recommended to me this package, its just perfect =)
