When installing the extensible SDK, we don't get to run the sanity checks until the "preparing build system" step; if they fail we tell the user to look at a log file. It would be nice if we could either tell them up front before starting the install process, or at least tell them what to do to continue the process (i.e. run ext_sdk_prepare.sh rather than having to reinstall the SDK).
We may also need to evaluate the sanity checks and determine if all of them make sense in an extensible SDK context.
