[Libvir] build problem

I'm having problems building the libvirt cvs bits (clean) on FC 7. I'm sure I'm doing something stupid?? I don't see xdr_qemud_packet_client anywhere in the source? Any ideas? Thanks, MRJ ../src/.libs/libvirt_la-qemu_internal.o: In function `qemuProcessRequest': /home/mrj/libvirt/src/qemu_internal.c:312: undefined reference to `xdr_qemud_packet_client' /home/mrj/libvirt/src/qemu_internal.c:375: undefined reference to `xdr_qemud_packet_server' collect2: ld returned 1 exit status make[3]: *** [xmlrpctest] Error 1 make[3]: Leaving directory `/home/mrj/libvirt.hg/tests' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/home/mrj/libvirt.hg/tests' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/mrj/libvirt.hg' make: *** [all] Error 2
