I think the requirements info should be updated to PHP 5.4 because this module uses is_a() php function in DynamicCacheControllerExtension.php file.
This function only accepts three parameters after PHP 5.3.9.
If you use PHP version below that, it will throw warning/errors like
s_a() expects exactly 2 parameters, 3 given
From PHP documentation:
The change Ia42e374202845dfe5e95c72512e9fefb4f00e789 introduced usage of is_a() with 3 arguments as from PHP 5.3.9.
