The license file itself never says "or (at your option) any later version". The license text of the GPL or LGPL is always the text of one specific version of the license. To know whether "or later" applies or not, you usually need to look at the comments in the code. In the case of cairo, they say: * This library is free software; you can redistribute it and/or * modify it either under the terms of the GNU Lesser General Public * License version 2.1 as published by the Free Software Foundation * (the "LGPL") or, at your option, under the terms of the Mozilla * Public License Version 1.1 (the "MPL"). If you do not alter this * notice, a recipient may use your version of this file under either * the MPL or the LGPL. Which indeed indicates LGPLv2.1 only, and not any other version.
