It's trying to reference berkeley DB from whatever path you compiled it with?? and it is missing a reference to libdb_cxx-4.8.dylib (it's not included in "Frameworks" subfolder of the application package as you might expect).

Important part:
  Library not loaded: /usr/local/opt/berkeley-db4/lib/libdb_cxx-4.8.dylib
