I downloaded the source of the fix from https://code.launchpad.net/~ubuntu-branches/ubuntu/lucid/xulrunner-1.9.2/lucid-security

However, compilation and installation gives the following error on Lucid Ubuntu 10.04.3 LTS

# dpkg -i xulrunner-1.9.2_1.9.2.27+build1+nobinonly-0ubuntu0.10.04.1_amd64.deb

Where can I get the fix?
