Hi inkscapers,
I've got some working XAR import/export .inx files for inkscape and a fairly usable two-way conversion of paths and basic properties.
I have tested the following instructions on a clean (base plus a configured cpan) chroot'd debian sarge. They should work as copy/paste installation on most *nix machines.

If won't work for you, the tarball is at the following link.

The build process is fairly straightforward, the copy/paste instructions are more convenient though because the bundle automagically fetches all of the prereqs off of cpan.
The exception is Image::Magick -- this is not currently a hard prerequisite, but you should really install it if at all possible. Not an issue on most machines with inkscape already installed?
Note the *.inx installation instructions at the bottom of the INSTALL file. The *.inx files don't install via the build at the moment.
Please let me know if that works for you or not and what platforms you're using.
Thanks, Eric
