You can still use all of the software mentioned in this HOWTO even if you are not using Debian. Unfortunately it will take a little more effort on your part to download and install everything. Fortunately it is really not that difficult. Most software packages include a README file when you gunzip them which will explain what you need to do to get things working on your system.
