Comment 65 for bug 575160

And that still points to distro specific cairo's that are used in the builds.

$ apt-cache policy libcairo2
libcairo2:
  Installed: 1.8.10-2ubuntu1
  Candidate: 1.8.10-2ubuntu1
  Version table:
 *** 1.8.10-2ubuntu1 0
        500 http://us.archive.ubuntu.com/ubuntu/ lucid/main Packages
        100 /var/lib/dpkg/status

Builds that use the mozilla cairo(s) are not affected.
