Sorry for the late reply. We are extremely busy right now.
We have tried many different options after posting that how-to. Some of
them work to some extent. However, for the time being, we have been
unable to produce a fully-functional binary.
We will keep trying as soon as we find some time and posta new how-to
here in case we find an improved procedure.
