How can I install Samba-3.0.25a in QNX 4.25

I have download samba-3.0.25a,but i don’t know how to install it for QNX4.25
and QNX 4.25 install CD have samba server source??

To my knowledge samba 3 has never been ported to QNX4 and I think it would be quite challenging.

Version 2.?.? is available somewhere on It think it might even be on this site.
