To install xfig, you need to use the GUI package manager which is accessible via the Mandriva Control Center (labelled as "Configure Your Computer" in the Mandriva menu). Search for xfig, select it for installation and when prompted, insert your installation media into the cd/dvd drive so that the installer can find the package. If you have a good internet connection, then go to
easyurpmi and setup the various main, contrib, plf and updates software repositories, so that the Mandriva package manager can also fetch packages from the internet.
