Installing 21.2.x in parallel with 21.1.x

I built and installed 21.1.x from sources and installed it off of my home directory (prefix=$HOME). I also installed all the packages in the default locations relative to my home directory. I'd like to download the latest beta release from the CVS server and install it (and it's associated packages) such that it will not conflict with my 21.1.x installation. How can I do this? I did read the web pages at cvs.xemacs.org but I'm not sure how I can follow these instructions and keep the two installation safely in parallel.
