[Cooker] pb with gramps

[Florent BERANGER]

  Hello, 
  
Here the error message I have when I try to launch gramps (genealogical  
software) :  
  
bash-2.05b$ gramps  
Traceback (most recent call last):  
  File "/usr/share/gramps/gramps.py", line 33, in ?  
    import gtk  
ImportError: No module named gtk  
bash-2.05b$  
 
Thanks for help, 
 
  Florent
