zhone debian sid

[A.A.]

Hi,

I have installed debian sid and zhone on my freerunner gta02.
When I run zhone it result:

Traceback (most recent call last):
  File "/usr/bin/zhone", line 74, in ?
    import cairo
ImportError: No module named cairo

what's the problem?

PS i have installed python-cairo
