Create a port for simplepie to keep it updated and use modular version
Simple build process:
Clone from https://github.com/simplepie/simplepie.git
run "php build/compile.php" from inside the clone dir
Results in SimplePie.compiled.php which can be placed, along with the LICENSE.txt, in an appropriate location.
The include in www/widgets/widgets/rss.widget.php will need updated to the new path/filename
Currently it resides in /etc/inc/simplepie but it should be in a more hier(7)-friendly location.
