Ah, we already got a check in EVPN's reload_controller:

    my $bin_path = "/usr/lib/frr/frr-reload.py";

    if (!-e $bin_path) {
        warn "missing $bin_path. Please install frr-pythontools package";
        return;
    }

hmm true, one would only see if the current node one is connect
through supports it, a warning (or error) on apply could be better
then, should ideally happen as early as possible though, to not roll
out a partial state.
