If you mean that a process with the variable PERL5LIB calls a
sub-process (another shell, if you will), which changes the variable and
exports it, yes.  The changed value is only available to the subprocess.
 The calling process' version of the variable is never changed.  This is
expected behavior.  "Exporting" only makes the changed value available
to the current process and any process spawned from that process, not to
any parent processes.
