Could there be an older libmm-glib lying around somewhere that's getting
linked in, instead of the one from git master?  If you're building git
master, you'll need to make sure that both the plugins and libmm-glib
are installed in the right place on the system, since I'm not sure that
just running the libtool wrapper will always work...
