Another way to get it are the Update Magma-Lists:
http://draketo.de/dateien/phex_win.magma http://draketo.de/dateien/phex_osx.magma http://draketo.de/dateien/phex_other.magma
Just enter it as URL-Download, and Phex will always get you the newest Version for your System.
At least till I updated the URLs to work via SVN, then it will all be hosted on SF.net again.
Even if none of teh servers should be avaible, Phex will connect to my computer and request it from here (and by that way it will get additional sources).
