Geo::TigerLine is a module around the TIGER/Line geographic data generated by the U.S. Census. TIGER/Line data files contain detailed information about roads, waterways, political and property boundaries, street addresses, etc. Almost (but not quite) everything you need to recreate something like Mapquest. Geo::TigerLine has been updated to reflect the structure of the 2003 TIGER/Line data sets. If you want to use older datasets, consider regenerating the TIGER/Line data set parsers with the mk_parsers script distributed with this module.
