You forgot one detail here:
 - QtLocation does not compile on Mac (as of yesterday morning)

Similarly, any user program that tries to compile a library with CONFIG -= qt 
with another that is CONFIG += qt will fail.

We need a fix somewhere.

I'd rather our default package produced binaries that work on 10.6. There 
needs to be very good reasons why the standard binaries produce applications 
for 10.7+.
