Ruby extension and SketchupAPI

Developers SketchUp SDK

I managed to build the basic Hello World ruby extension from Github with XCode 7.2.1

Now I would like to add some of the functions from SketchupAPI and to do this I have initially included the headers

#include "RubyUtils/RubyUtils.h"
#include <iostream>
#include <assert.h>
#include <SketchUpAPI/common.h>
#include <SketchUpAPI/model/material.h>
#include <SketchUpAPI/color.h>
#include <SketchUpAPI/geometry.h>
#include <SketchUpAPI/initialize.h>
#include <SketchUpAPI/unicodestring.h>
#include <SketchUpAPI/model/model.h>
#include <SketchUpAPI/model/entities.h>
#include <SketchUpAPI/model/face.h>
#include <SketchUpAPI/model/edge.h>
#include <SketchUpAPI/model/vertex.h>
#include <vector>

VALUE hello_world() {
  return GetRubyInterface("Hello World!");
}

// Load this module from Ruby using:
//   require 'SUEX_HelloWorld'
extern "C"
void Init_SUEX()
{
  VALUE mSUEX = rb_define_module("SUEX");
  rb_define_const(mSUEX, "CEXT_VERSION", GetRubyInterface("1.0.0"));
  rb_define_module_function(mSUEX, "hello_world",
    VALUEFUNC(hello_world), 0); 
}

The project builds successfully, I copy the three files in my plugin folder …/Plugins/RG/SUEX

Frameworks/Ruby.framework
Frameworks/SketchUpAPI.framework
SUEX.bundle

but when I require it with require "RG/SUEX/SUEX.bundle" I get the error

Error: #<LoadError: dlopen(/Users/ruggiero/Library/Application Support/SketchUp 2015/SketchUp/Plugins/RG/SUEX/SUEX.bundle, 9): Library not loaded: @rpath/SketchUpAPI.framework/Versions/Current/SketchUpAPI

I think the problem is related to the search path but I cannot figure out how to fix it. Any idea?

Any hint on how I can fix the problem above? Is it actually possible to use the Sketchup C API from Ruby to build extensions that work on the current model?

Thanks
