We have plists and roots for 10A432 and 10B504. We are only missing 2 roots, IOFWDVComponents and Libmx, and hope to have those builds fixed soon. I added libdispatch to the plists, but you will have trouble building the project due to missing Block_private.h. Until we package up something "official", you can find Block*.h at llvm.org: http://llvm.org/svn/llvm-project/compiler-rt/trunk/BlocksRuntime/Block_priva... As for building the projects yourself, a quick first pass showed 301 failures. I'll be investigating those over the next week or two and hope to have most of them cleaned up soon. At this point, if you try to build something and it fails, I already know about it, so please hold off on flooding the ticket system for now. Thanks -Bill
