I think you can't reasonably expect a module author to figure out the minimal required version number of perl and all the other modules the module depends on. That would be too tedious. I can understand if the module author errs on the safe side and specifies version numbers he or she is sure will work. That way, people who want to work only with stable software will get no unexpected errors.

You can of course still try to use a module if you don't have all dependencies satisfied. If you are sure the module works that way and doesn't depend on anything newer, the best thing you could do is write to the module maintainer, who will change the dependencies.
