=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>.

So if you are getting strange test failures, you may want to try

=head1 Coexistence with earlier versions of perl 5
-Perl 5.10 is not binary compatible with earlier versions of Perl.
+Perl 5.11 is not binary compatible with earlier versions of Perl.
In other words, you will have to recompile your XS modules.
In general, you can usually safely upgrade from one version of Perl (e.g.
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
- sh Configure -Dprefix=/opt/perl5.10.0
+ sh Configure -Dprefix=/opt/perl5.11.1
-and adding /opt/perl5.10.0/bin to the shell PATH variable. Such users
+and adding /opt/perl5.11.1/bin to the shell PATH variable. Such users
may also wish to add a symbolic link /usr/local/bin/perl so that
scripts can still start with #!/usr/local/bin/perl.
subversions may not have all the compatibility wrinkles ironed out
yet.
