I'm not sure whether this would be the best way to solve the problem, but couldn't you install a file in /etc/ld.so.conf.d for xulrunner-1.9.2 so that the appropriate directory is included in the library search path? A related bug, from which this suggestion comes, is https://bugs.launchpad.net/ubuntu/+source/xulrunner-1.9/+bug/557275.
