That was I am doing at the moment and face some problems with my init
files, problems I don't face in emacsformacos. Since I was unable to
have my favorite lucid option compiled, I am not sure whether it would
be better to switch to emacsforosox (I will not use the Mac most likely
not for any development but more as backup solution of sorts)

Thanks for pointing this out.

First of all thanks for the detailed explanation which was extremely
helpful.

As far as the FAQ is concerned, I think that is a very good idea, may I
suggest also to include the information of how to add the rugby script
(as you did in a different email)?
