Recent mapserver releases have an internal version of AGG, which was forked in January 2009, http://trac.osgeo.org/mapserver/changeset/8984. The dependency on the agg package in https://projects.argeo.org/elgis/svn/factory/trunk/rpmbuild/elgis/mapserver/SPECS/mapserver.spec should not be needed, any more. Regards, Peter
