I take it Inkscape is working ?
Do you NEED these features ?
How did you install Inkscape ?
Which Linux distro/version/architecture ? (eg. Ubuntu 12.04 32bit)
If we're talking about an Ubuntu >= 12.04 based dstro ..
If you really must, you should be able to get rid of the fig2dev
dependency message by installing transfig[/code:
sudo apt-get install transfig
But there's no easy way of satisfying the skconvert
dependency .. that's part of the skencil
package, which doesn't appear to be in the repos.
But I don't think either are necessary for Inkscape to work .. they appear to be just export filters, to export Inkscape drawings to other file formats.
