delocate fails when LC_RPATH is set to @loader_path

[chatziko]

Using a lib from ortools

$ otool -l libClp.1.14.3.dylib
...
          cmd LC_RPATH
      cmdsize 32
         path @loader_path (offset 12)

delocate-wheel is confused, searching for a directory names "@loader_path"

$ delocate-wheel dist/*

/usr/local/lib/python3.7/site-packages/delocate/libsana.py:110: UserWarning: Couldn't find @rpath/libClp.1.dylib on paths:
	/tmp/dist/@loader_path
  '\n\t'.join(realpath(path) for path in rpaths),

Same thing with:

          cmd LC_RPATH
      cmdsize 24
         path $ORIGIN (offset 12)

That's right, I'm afraid, we don't deal with @loader_path at the moment. I guess @loader_path is always the path containing the library expressing the dependencies.

Hacky workaround for anyone interested: create a symlink named @loader_path (the exact path is shown in the error message) to wherever the library is! delocate-wheel will happily follow it and find the library 😄
