framework dependencies & compiled binary

I modified some files in order to make it compile without any further modification.
It had an import of a file that is not in the repo. That line has been commented.
Also a compiled binary has been added to the repo.
Declaration of required framework dependencies has been added to module.xconfig (saving the developer to link manually their xcode project with these dependencies). However, libiconv.dylib does not link correctly and needs to be added manually. That's why I include a compiled version of the module, because is such a headache to compile yourself the module.
