[cairo] help needed in compiling python code

[gopinaths]

Hi,
    I'm having trouble executing example codes in examples/ in the
pycairo-0.1.3 package.

# ./cairo-demo.py
Traceback (most recent call last):
  File "./cairo-demo.py", line 4, in ?
    import gtk
ImportError: No module named cairo._cairo

cairo modules are available in /etc/lib/python/site-packages/
Could someone help me with the compile error..

thankx
