OK, older version of amule didn't Build-Depends on the libupnp*-dev
packages (but Depends on binary version of libupnp).

 From 2.2.2 amule appears to be able to link to libupnp at build time, so libupnp3-dev was added to Build-Depends (and libupnp3 removed from explicit Depends). Apparently 2.2.2 only support libupnp linked during built time and not dlopened, see comments from 2008-11-07 of:
