SimplePie library is required for Feeds SimplePie Parser The Feeds module is reporting a warning about needing a SimplePie parser and prompts the user download a compiled version of it, but it isn't clear how/where to do this.

Where can I find the compiled version of the required library?
You can pull a compiled version of the parse from http://simplepie.org/downloads/simplepie_1.3.1.compiled.php. Rename this file simplepie.compiled.php and copy it in the  directory sites/all/libraries/simplepie/; the module should stop reporting the error.
