The short answer is: Don't.
The long answer is: It depends when/where you want to change it. If you
want to do it on your machine just once up front, chmod is your friend,
albeit a scruffy, disreputable one that your parents don't like you
hanging out with. If you need your program to be able to do it at
arbitrary times after installation (because the permissions will be
reset on that directory if the user runs a Repair Permissions process or
installs an OS update) you need to see option (c) above. At which point
the real answer would just be to use that technique to write your pref
without compromising the security and stability of the system.
