Hi,
I normally add a link to an Inkscape binary (either the RPM or the Autopackage, whichever turns up first) in the Inkscape Zero Install feed:
http://0install.net/2006/3rd-party/Inkscape.xml
However, there don't seem to be any Linux binaries this time, so I have added the source to the feed and compiled two binaries myself (x86 and x86_64).
These can be run using this command:
0launch http://0install.net/2006/3rd-party/Inkscape.xml
The correct binary for your platform will be selected automatically (ensure "Help test new versions" is on, or you'll get 0.45). The 0launch command is provided by most Linux distributions, or you can get it from:
Alternatively, you can use the binaries without using 0launch by going to the web-page above and clicking on one of the download links. The binaries are compiled with binreloc on, so you can run them directly after unpacking. I've tested them on Ubuntu/Hardy, but I don't know if they'll work on anything else.
To choose a different version or compile from source:
0launch -g http://0install.net/2006/3rd-party/Inkscape.xml
When compiling (right click -> Compile), Zero Install will download the headers for GTK, GLib, Pango, ATK, GTKmm and GLibmm automatically. However, some other libraries are not available this way and must be installed manually first as root, e.g.
$ sudo apt-get install build-essential gettext libpng-dev libgc-dev libfreetype6-dev liblcms-dev libsigc++-2.0-dev libcairo-dev libcairomm-1.0-dev libxslt-dev libboost-dev libpopt-dev
Hope that's useful!
PS: The Zero Install feed is currently listed under "Development Versions" on http://inkscape.org/download. In fact, it only lists official releases, so it should be moved to "Official Release Packages". Cheers!
