I want my app to run on 10.2.8, and apparently this means I have to
remove the frameworks from the project and replace them with Other
Linker Flags of
-weak_framework Carbon -weak_framework SystemConfiguration
After working around what I recall is a known bug (remove the \
that gets added), my project which used to link now has errors:

I'm not using long double anywhere in my code that I'm aware of
(though it could be in some of my libraries). Where do I pick up
these symbols?

You are probably trying to link against a library build with gcc/g++ 4.0
4.0 supports long doubles, 3.3 don't
