Redmine

Hey guys,

I have an existing redmine installation running on Debian Lenny, It was set up using this guide here
http://madpropellerhead.com/random/20100820-installing-redmine-on-debian-with-apache

When it was set up we didn't need subversion we just needed bug tracking, now we need to integrate subversion with redmine,

Is there a best practice way to install subversion for use with redmine, I've looked through the installation guides but as far as I can tell they all assume subversion is already installed

any help or pointers would be great

Cheers

Scott
