Note that you can usually just add a compiler flag that turns these
errors back into warnings so that you don't need to touch framework code
to get this job done.  Its not a bad thing to "fix" that code if the
warnings are good, but it you can avoid a framework patch to get your
job done, that's better.

Which kernel version did you end up with?

Is the default shell on that system bash?  We sometimes end up assuming
bash when we shouldn't.

Chris is right, sometimes there are bootstrapping issues with adding new
software platforms where you have to do stuff to get the project exports
redone from the project that the new platform is in.
