perl-suid 5.8.8-7ubuntu2 (amd64 binary) in ubuntu gutsy

 suidperl is a setuid root helper program which is invoked by perl when
 executing scripts with setuid/gid bits set on systems (like linux) which
 don't have support setuid script execution natively in the kernel.
 .
 Usage of this program is now strongly deprecated upstream and support
 (along with this package) will probably be removed in 5.10.
