=head2 suidperl
-suidperl is an optional component, which is normally neither built
-nor installed by default. From perlfaq1:
-
- On some systems, setuid and setgid scripts (scripts written
- in the C shell, Bourne shell, or Perl, for example, with the
- set user or group ID permissions enabled) are insecure due to
- a race condition in the kernel. For those systems, Perl versions
- 5 and 4 attempt to work around this vulnerability with an optional
- component, a special program named suidperl, also known as sperl.
- This program attempts to emulate the set-user-ID and set-group-ID
- features of the kernel.
-
-Because of the buggy history of suidperl, and the difficulty
-of properly security auditing as large and complex piece of
-software as Perl, we cannot recommend using suidperl and the feature
-should be considered deprecated.
-
-Instead, use a tool specifically designed to handle changes in
-privileges, such as B<sudo>.
+suidperl was an optional component of earlier releases of perl. It is no
+longer available. Instead, use a tool specifically designed to handle

libraries after 5.6.0, but not for executables. TODO?) One convenient
way to do this is by using a separate prefix for each version, such as

may also wish to add a symbolic link /usr/local/bin/perl so that
scripts can still start with #!/usr/local/bin/perl.
