How do you expect all ports to respect DESTDIR in their Makefiles,
while many ports don't even use make? As I've said, that will require
tremendous amount of hacking and is not even possible sometimes.

Truss uses ptrace(2). There are other facilities, but they are less
useable - ktrace (produces too much output, needs to be enabled in
kernel) and dtrace (only available in current for now, also should
be enabled in kernel).
