Redmine

Hello all. I'm sure, as with most things written on the internet as the nature of info is that it's ever-evolving, the links need updating as the stealthymonkeys.com website doesn't seem to be maintained. Here's the link for those curious:
HowTo_install_Redmine_on_CentOS_5
The portion of the HOWTO that discusses the installation of the rpm, that link is here:

RHEL/CentOS 6

rpm --import http://passenger.stealthymonkeys.com/RPM-GPG-KEY-stealthymonkeys.asc
yum install http://passenger.stealthymonkeys.com/rhel/6/passenger-release.noarch.rpm
yum install mod_passenger

Can anyone please confirm what the updated information should be for those of us still using Redmine?

Thanks and regards.
