We may have gotten an error message like:

  videoSetGamma(): Failed loading udev_device_get_action:
      (...)/libSDL2-2.0.so.0: undefined symbol: _udev_device_get_action

But:
 1. The "error" in question did actually happen earlier in SDL, but is harmless
    because SDL first tries to load a symbol using 'dlsym(RTLD_DEFAULT, ...)' and
    failing that (as it happens in my case), from an explicitly loaded libudev
    (which succeeds).
 2. The message misleads a user into thinking that it may have something to do
    with gamma adjustment having no effect. (As is the case for me.)
