Don't forget to "sudo port clean libsdl2" before trying again.
According to http://www.openradar.me/12772011 it looks like indeed NSWindowDidChangeBackingPropertiesNotification and NSBackingPropertyOldScaleFactorKey were added in OS X 10.7.3, the release date for which was February 1, 2012. Xcode 4.2 was released October 12, 2011 so it would not know about those. Xcode 4.3 was released February 16, 2012 and would presumably contain these constants.
