CSS3 JS not loading

Running the code on my localhost, and unable to get the CSS3PIE to load anything to the header; in fact there are Recent Log Messages describing a missing file of url '/css3pie/css3pie.js' -- it was looking in the root directory.

Examining the code of the module, and changing line 102 to be :

$path_to_css3pie_js_file = variable_get('file_public_path', conf_path() . '/files'). '/css3pie/css3pie.js';

then enables the module to work as expected. For some reason 'public://' doesn't translate on my system?

Hope this helps somebody!
