If a CPAN user has been active on other distributions they are maintainer of, my experience has been for the most part that it'll at least be looked at. It may not be worked on right away, but at least you know they're doing work. If a response isn't received in a reasonably timely fashion, it doesn't hurt to ping the author via their point of contact (email, usually) as a polite request.
People get busy, and sometimes see the bug email come in, but shuffle it away and then forget about it until the submitter or someone else who's hit the bug reaches out. It happens... I know ;)
