Where place spyc library dependencies

Question

I have a issue trying to activate REST SERVER from services. I need to add this library. I'm using drupal 7.19 on Ubuntu.

Reading this question, I add the spyc.php in 'servers/rest_server/lib/'

But where I must place the rest of files?

Reading the issue, #2 suggest that the best solution will be allow to place the library on 'sites/all/libraries', this doesn't work in my version.
