I am not sure this is true, as I am running the stock pycairo 1.4.12 and 
everything seems to work fine. I simply install python-pygoocanvas through apt 
and everything seems to work without taking extra steps, or installing libraries 
from source. If you find yourself having to do this sort of thing on a system 
like ubuntu, stop, take a deep breath, retrace your steps and figure out where 
you went wrong.
