Well, Fedora has yum, which automagically handles dependencies. I thought the most prominent deps for Inkscape were the GTK-mm libraries... for build, as it is "statically linked" to them, last I knew it included the subset of gtk-mm it used, being "self contained", so it would not need gtk-mm as such to use the program, though it would be necessary for building the program from source (like if building from CVS)
