Therefore, you need to link in -pthread on -STABLE or -lc_r on -CURRENT. If you're building your own app, you should be using either pkg-config --libs libxml-2.0 or gnome-config --libs libxml-2.0 to get the libraries needed for libxml2. If this is a port in the system, let me know which one is failing.
