I finally got csound5 to compile from source on 64studio, I had to install a bunch of things from source to get it to work, but once I went through the sequence of installations to make sure I had all my libraries now I have csound5 working with dssi and jack support on the debian flavor of 64studio.

Despite what people say about linux being harder, if you know some C programming, linux is easier than windows, as you can provide your own solutions :-).
