Usually this means that you haven't added the new utility functions to
src/libvirt_private.syms. Find the section for the source file the new
function was added to, then add in the name of your new function with a
semicolon at the end of the line. Be sure to keep the names in
alphabetic order (within each file) lest you incur the wrath of Eric! :-)
