Insecure dependency in %s
           (F) You tried to do something that the tainting
           mechanism didn't like.  The tainting mechanism is
           turned on when you're running setuid or setgid, or
           when you specify -T to turn it on explicitly.  The
           tainting mechanism labels all data that's derived
           directly or indirectly from the user, who is
           considered to be unworthy of your trust.  If any such
           data is used in a "dangerous" operation, you get this
           error.  See the perlsec manpage for more information.
