Where place spyc library dependencies 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.
The problem was I hadn't the dependency libraries . Just downloading this module, updating, and adding the spyc.php in 'servers/rest_server/lib/' Rest server will work.
