Justin, I worked on the kit this morning. Here is where I am leaving it:
1. The build number was not set in RC2 when you build it. You can see this because the build number is not set in flex-sdk-description.xml (and there none of the Version.as files). See build/build_release.sh for how I did it for 4.8.0. 2. apache.swc and experimental.swc were missing from the binary kit so I added them. 3. I add a java source and target of 1.6 to the compile target in the batik build file so if you build the compiler with Java 1.7, FlashBuilder 4.7 seems happy. 4. makeApacheFlexForFlashBuilder.sh works with the new binary kit which includes #2 and #3 and FB 4.7. 5. We did not make a decision on what version of AIR to recommend/run mustella with. I think AIR 3.1 is too old. I've been using AIR 3.4 for about a month now. I'm pretty sure AIR 3.5 is just about to be released. I think we need to pick a newer version, update the README and the URL in makeApacheFlexForFlashBuilder.sh/bat and update our AIR_HOME global variables/env.properties files to use it. The installer should be updated as well. Carol
