Why don't CPAN.pm and cpanminus update modules, even if they know about newer modules?
learned something new today from akoenig: usually there is a reason for a module not getting indexed, and the author gets an email with that reason.
But in case of HTML::Template 2.9 -> 2.10 it's just that 2.10 is a lower version than 2.9, unfortunately.
So whenever you are missing a module in the index, the author has probably gotten an email about that, but it doesn't hurt to create a bug report (emails get lost, bug reports don't =)
