Hi,

The _cairo.so file is made to be imported (implicitly) as "cairo._cairo" 
as its Python name. But it’s really an implementation detail. You should 
also have an __init__.py file next to it that contains something like 
"from ._cairo import *" (Note that this is a relative import.)

You’re not supposed to have …/site-packages/cairo in your PYTHONPATH. 
"import cairo" should instead import the cairo/__init__.py file, which 
in turn imports cairo._cairo.

Cheers,
