Package: dh-make-perl
Version: 0.63
Severity: minor

is_core_module() is properly reporting core modules but also in future versions of Perl.
For example module that is dependent on "Module::Build: 0.3603".

$ perl -MDhMakePerl -le 'print DhMakePerl->is_core_module("Module::Build", "0.3603")'

here is a patch that will not consider any higher version than currently running Perl
a core module:
