This is a bug in xvidcap; it requires a modern dbus-1 but its configure script doesn't complain if yours is too old -- even though the rest of the code can be compiled with no dbus support at all.

It also doesn't seem to understand --without-dbus-1, but if you temporarily go and rename /usr/lib/pkgconfig/dbus-1.pc to something else, then configure and build xvidcap, you should get a dbus-less version. (That assumes, of course, you don't actually need whatever xvidcap's dbus-related functionality is -- if you do, you're in deeper trouble.)
