   Are you using "su" or "su -"?

A setuid binary ignores LD_LIBRARY_PATH for security reasons.

Hmm...  I hate to sound too critical here but I can't restrain making
comments about that command line.  It is working very much too hard to
perform the function of listing out a directory with the inode change
timestamps listed.  (And also that is not sufficient to solve the
original poster's question either.)  But back to that command line...

> TMP=`ls -Aa`

The ls -a option overrides the -A option.  Therefore 'ls -Aa' is the
same as 'ls -a'.  But you probably wanted 'ls -A' there.

> for x in $TMP ; do

Of course files with whitespace in them cause trouble here.  An extra
splitting is introduced here that will split files with whitespace
apart.

> echo -n "$x - "

Use of 'echo' with options is a portability nightmare.  Better to use
'printf' in that case.

> stat $x | tac | head -1

This is functionally the same as asking stat to output only the time
of last change directly.

  stat --format %z $x

> echo "" 

why the extra blank line?

Overall this is almost the same as using 'ls' directly.

  ls -Aclog

Oh... I didn't know that, but now I do!  Thanks!

I'm using just su... should I use "su -" ?

   If you use "su -", it does the equivalent of logging in, and thus
   reads .bash_profile; "su" by itself doesn't.
