This an attempt to create a dynamic shared library w/ a two-level  
namespace & undefined symbols (cpp_main is a "call-out" from the  
library code). Not allowed. Must state the library (an "umbrella  
framework" usually) to  resolve from at dynamic link time.

I think this can be solved by shifting to a flat-namespace. I will try.
