  The SHLIB_PATH is ignored if a process has a different effective user
id than real user id (or different effective group id and real group
id). If you run a setuid program with the real user id already matching
the owner of the file, then the setuid bit won't matter. The real and
effective ids will continue to match. The SHLIB_PATH will be used in
that case.

  It should not matter whether you use login or su to get to the right
user id.
