Is it possible to port Mac apps to other BSD operating systems?

Mac OS X is one flavor of BSD Unix. As Borelaid already pointed out, that does not necessarily mean that porting Mac apps to other flavors of BSD would be easy or even manageable, much less so than between other common BSD flavors. Every one of them brings their own specifics, and OS X more than most.
