Just for grins I tried installing LibreCad using Sourcery today and it worked. I had tried a few days ago after installing muParser and it didn't finish installing - forget what the error was and I didn't write it down (shame on me).
If someone somewhere did something - thank you, if not - just remember - you got to hold your mouth right
SalixOS64 xfce, with multilibs installed per instructions, wine and virtualbox working - I'm a happy camper
