On OS X MacPorts currently has 0.12.1, but looking at the revision log of the portfile it seems actively maintained and has seen 9 version updates in the last 12 months. I expect the new 0.12.2 will soon be the current version in MacPorts too. (This only concerns mac users that compile Inkscape themselves, the packages from sf.net include the library similar to the windows installer).
