mandriva's next version (2010.0) is now in version freeze, for a release date in early november. this means that current packages are not allowed to be upgraded to latest version, unless there's a compelling reason to do so (security update, crash or big regression).
there is still, however, the possibility to ship new packages. so if you miss some perl modules in mandriva and you really want them available as rpm packages in 2010.0 version, now is the time to speak up! just add your request as comment to this post, and i'll do my best to fulfill it.
