It can't.  This is a specific instance of a more general
situation: it is impossible for a subprocess to modify its
parent's environment, or current directory, or other per-process
state.  This is the reason that, for instance, "dircolors" and
"ssh-agent" work by writing a series of shell commands to stdout
(which must then be evaluated using `eval' or similar), not by
directly setting the variables it needs to set.
