The lessphp is no longer contained in the module.

If you are updating, you can just copy the new version on top of the old one and it will still use the previously existing bundled copy of lessphp, or the version in your Libraries folder if installed using the direction on the project page.

If you are installing new, follow the directions on the project page for how to download and install this module and is required libraries.
