I would rather have a wise and experienced developer X than a developer with Y experience in Z. As long as you are hiring people with skills in solving similar problems to the ones you are having or are anticipating on having. Edit: However that may not work for you.

The presumption is that one believes that a senior Perl developer really exists.
