NOTE: in the above script you'll want to replace '-isysroot$SDKROOT' with '-isysroot $SDKROOT' (minus the single quotes). Essentially adding a space after -isysroot. This caused me hours of frustration, hope it helps someone else save some time.

Thanks for that catch...my apologies for the headache.
