Virtualmin Tarball

I'm currently running Slackware 12.1. I have all of my dependencies for Virtualmin installed and ready to go. I have not been able to find a tarball download link for the pro version of Virtualmin however. This is very frustrating. I looked in the Virtualmin repository. However, I only see OS specific RPM packages (yuck)! Where might I find the latest tarball for the completion of my manual install on Slackware 12.1? Thanks in advance. ;)
