How do I load dylib (i.e. phobos and druntime for ldc) in Macos sandboxed app?

[David]

This is more a macos thing than a D thing but still relevant. In 
another thread I was asking about cleaning up a D dylib for using 
in Excel. Ldc was suggested though first I have to figure out how 
to make the phobos and druntime loadable from within the sandbox.

(I've posted in a new topic as it was drift from the original 
question - hope that helps anyone else searching for the same 
answers).

I'm not expecting many relies - unless someone has happened to 
have solved it. Will post links once I've figured a solution.
