+>> Thanks. Now I see. NetBSD and DragonFly and several other systems don't have /usr/bin/perl so that path is replaced in the sh-bang lines of various scripts. So it doesn't match in the pm_filter expression. Can you please consider providing a variable or not matching on that assumed path to perl.
