Compatibility

Hi. I'm trying to install this 3rd party content management system called Concrete5. I was wondering what PHP settings I will need to change, and how to do it. It says that it needs the following before I can install:

* PHP 5, including:
o GD support
o SimpleXML support
o Search indexing with Lucene (an optional but integrated feature) requires the mbstring extension installed in PHP.
o PHP with short tags enabled (you should be able to set this setting in .htaccess if necessary.)
o All magic quotes, including magicquotesgpc DISABLED.
* Python 2.2 (only required by HTMLDiff, which is used when comparing multiple versions of pages.)
* MySQL 4.1 or higher


Is the default install of Dreamhost compatible with these features? Will I need to turn off magic quotes? How do I go about doing that?
