551697 Install modules / extensions to PHP 5.3.5 on Dreamhost 2

I'm trying to run Amazon Cloudfront CDN for my website (via W3 Total Cache). I'm hosted on Dreamhost with PHP 5.3.5 and FastCGI, I'd like to add the following modules to my PHP: EXTENSION 1 - HTML Tidy extension: Not installed (required for HTML Tidy minifier suppport) I think this requires compiling a new version of PHP?
