The included dylibs are automatically included based on what the included objects are linked to, so they are not good to rely on, because they can change in a given version.

I forgot to say, it will be relocatable once all of the libs in gridflow/libs are set to @loader_path/libs/, i.e.

install_name_tool -change \
  /Library/Pd/gridflow/libs/libglib-1.2.0.dylib \
  @loader_path/libs/libglib-1.2.0.dylib \
   /Library/Pd/gridflow/gridflow.pd_darwin
