We have made still-experimental-but-probably-working Debian repository with daily built Orange packages. Currently without add-ons.
To get access to those packages just add those two lines to your /etc/apt/sources.list (this file contains a list of repositories with packages):
deb http://orange.biolab.si/debian lenny main deb-src http://orange.biolab.si/debian lenny main
And then you can install Orange with this command:
aptitude update aptitude install orange-svn
Packages are not signed as they are made automatically so you will probably be warned about this.
Those packages will probably work also on other Debian-based Linux distributions like Ubuntu, but have not yet been tested there. Please test it and report how it goes.
You can also get source of those packages with this command:
apt-get source python-orange-svn
And then build package by yourself in extracted source directory with:
For example this will be useful on amd64 platform for which we currently do not yet provide binary packages. (Edit: now we provide binary packages also for amd64 platform.) But we will once we see how well this system works.
