I noticed that the problem only manifests itself if x11vnc is ./configure'd before compilation with the "--with-system-libvncserver" option. Unfortunately, only removing this ./configure option is not sufficient. One needs to make two other modifications to the debian/rules file.
Recompiling the x11vnc package after patching the debian/rules file with the attached patch produces a working x11vnc binary.
