On http://wiki.inkscape.org/wiki/index.php/Installing_Inkscape#Slackware_Linux "I used the precompiled rpm provided by Inkscape for the 0.44 release as my gcc wouldn't compile it. All you need to then do is run rpm2tgz at the command line on the package, eg " rpm2tgz inkscape-0.44-0.i686.rpm" and then install with "installpkg inkscape-0.44-0.i686.tgz"."

I'm not yet a *NIX developer, but sense that there may be a more generic set of instructions hidden in this specific tip. Would it be correct to say, 'RPM packages can be used to install Inkscape from a GNU zipped tar ball (.tgz) by using the appropriate converter utility, rpm2tgz, after retrieving the rpm. Thus, "rpm2tgz inkscape-0.44-0.i686.rpm" produces inkscape-0.44-0.i686.tgz, which can be installed with "installpkg inkscape-0.44-0.i686.tgz".' The title of the section, I imagine, could then be something like, "Converting an RPM package for installation as a GNU zipped tar ball (.tgz)".
