Go to the
http://rpm.pbone.org site. Select advanced search, clear all the boxes and click on "SuSE 10.x" and "SuSE Other". There is an Inkscape package prepared for SuSE 10.0.
Click on a link that has 10.0 in the link. The dependencies are listed on the next page with links where you can download them, although they may be on your install discs. The site can even examine you system and highlight the dependencies that you need. By the way, there is no libgc in the dependency list for the 10.0 version of Inkscape.
You might also want to add the repository as a YaST source, if the repository has packages that aren't on your install discs. Then you can later install packages from this repo using YaST.
