Hi! I hope that this is the right place to fill this bug report Homepage of x11-plugins/gkrellm-hddtemp should be changed from: http://coredump.free.fr/linux/hddtemp.php which is a 404, to: http://www.guzu.net/linux/hddtemp.php (if you visit http://coredump.free.fr/ it will inform you about the url change)
Thanks, fixed in CVS.
