I noted this issue in another thread but thought it might help a few people if it was a thread with the specific title as shown.
I downloaded the AIR 3.2 SDK from the final release link and all of the file dates within are earlier than the files in the pre-release version: air3-2_p6_sdk_mac_022712.tbz2.
Given the messy state of trying to merge folders in the Mac Finder I'm going to hold off installing v 3.2 until I'm sure it's the correct version.
Is fixed now. Thanks Adobe.
Thanks for reporting back. I was just about to post letting you know that it should have been fixed an hour ago. If you encounter any other problems, please let me know and I'll investigate.
