So it appears I need some other packages in order to get the guest additions to fully install on the latest sun vbox. So if anybody can link me to a wiki that is mentioned in another thread on this process. I am a fairly experienced nix user so I looked around and in-spite of this I am stuck.
Figured it out, always seems to happen once you post eh, used this link for future reference.

Which I think is the mentioned wiki.
Salix looks interesting.
