[libvirt] Problem building on Fedora Rawhide

I just checked out a clean tree on a Fedora Rawhide system (up to date as of today), and ran "./autogen.sh && make", and ended up with the following error. Am I missing something, or is configure missing something? make[3]: Entering directory `/home/laine/devel/libvirt/daemon' CC libvirtd-event.o CC libvirtd-libvirtd.o CC libvirtd-remote.o CC libvirtd-dispatch.o CC libvirtd-stream.o CC libvirtd-remote_protocol.o CCLD libvirtd ../src/.libs/libvirt.so: undefined reference to `g_pfnGetFunctions' ../src/.libs/libvirt.so: undefined reference to `g_pVBoxFuncs' ../src/.libs/libvirt.so: undefined reference to `VBoxCGlueInit'
