Hmm, after an hour of dpkg, easy_install, git clone and all sorts of
dependency problems I finally got:

cairo.cairo_version_string() == '1.9.2'

and then I got a segfault.

I'll try it again when there is a Ubuntu repository for it. (is
there?) I tried to upgrade cairo on my system before. When it broke I
found out how many programs depend on cairo. :-)

I do have fun! See attachment. It's for a web-to-print system so I
could send you the real thing. :-)
