Hello,

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.

Kind regards.
