the compiler dependency, you may need to also add "-Dcc=...".

-Perl 5.21.5 is not binary compatible with earlier versions of Perl.
+Perl 5.21.7 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/perl5.21.5
+ sh Configure -Dprefix=/opt/perl5.21.7
-and adding /opt/perl5.21.5/bin to the shell PATH variable. Such users
+and adding /opt/perl5.21.7/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.
