In general, no, it is not difficult at all. As long as you stick to the POSIX (and other open standards) and use a conformant compiler for the software there shouldn't be any problem in porting software.
I do it all the time - from Linux to Unix, or Unix to Linux, makes no difference. In fact, a lot of common software is cognizant of the actual Operating System at compile time and will take care of the differences (if there are any).
