Per Perl's compatibility and support policy, minor releases of Perl 5 such as Perl 5.16.0 and 5.16.3 share the same level of binary compatibility, while major releases of Perl such as Perl 5.14, 5.16, and Perl 5.18 do not share binary compatibility. That is to say, modules built and installed for one major version of Perl are not necessarily compatible with modules built and installed for another
