You can find our x2go - Debian Repository here: http://x2go.obviously-nice.de/deb/ The most recent release "Uthörn" is described as pool-lenny. You'll need to add this line to your /etc/apt/sources.list

deb http://x2go.obviously-nice.de/deb/ lenny main

and you'll need to update your package database:

apt-get update

You'll also find the source packages inside the repository which are named "*.tar.gz".

You'll need to add two repositories to your "softwaremanager" application:

# x2go Reopsitory
Web address: http://x2go.obviously-nice.de/deb
Distribution: diablo
Components: main

# QT Reopsitory
Web address: http://repository.maemo.org/extras-devel
Distribution: diablo
Components: free

You'll need an installed X-Server to use this client. You may use the application "X11" which is shipped with Mac OS X 10.5.6.
