As long as you always know that something returned by record_get_person may not be freed by your program, you can attack the problem by having two classes, Person::OwnedByPerl and Person::OwnedByLibrary. The destructor for Person::OwnedByPerl would call free_person(), while Person::OwnedByLibrary would have no destructor.

Of course, you could also store that information of whether to free the person or not on the XS level by having a struct hold the person pointer and a flag whether the XS owns that person or not.
