Dual-lifed means the module is available both on CPAN and as part of a Perl release. Most modules available as part of the Perl distribution start out as CPAN modules and are then "added to core" at a later point. However some modules see their initial release as part of the core distribution, and occasionally are then split out. This process is often called "becoming dual-lifed".
