This is the discussion thread. The source kit built for me on mac. I updated notice files. I think I solved the missing strings issue. Not sure about Carlos's crash. If you get a crash, re-run and right-click and turn on debug mode before continuing with the install. The output should end up in your flash log.txt file or in the console. Caching is possible for legacy builds.
Note that the problem about the flex-config.xml having the wrong player/swf versions is actually a problem in the SDK's installer.xml so it will require installing a nightly or an SDK RC3 someday to see that it works. Thanks, -Alex
