I can't understand what version of the LGPL you are using for the Wine source code. > Wine is free software. The licensing terms are the GNU Lesser General Public License. There are 2 links in your main page: the first links to the official LGPL v3 page http://www.gnu.org/copyleft/lesser.html the second links to a page of the WineHQ site, showing the LGPL v2.1 http://www.winehq.org/site/license Please, make thing clear.
