Since you said your need was urgent, I'll give you the answer I am pretty sure is correct in spite of not being an actual member of the Freebsd team. While binaries compiled on older versions of the OS should work on newer versions with a great degree of reliability, differences in the versions of the standard C libraries that newer binaries are compiled against (and other differences, especially in binaries like top) will sometimes prevent them from running on older systems. This problem is compounded as the time between the age of the system and binaries increases. I hope this information is of use to you.
