I've read about individuals installing SugarCRM on Yahoo! Web Hosting servers and was wondering if it was actually possible to do so.

I have tried to install SugarCRM on my Yahoo! Web Hosting server and get the following error:

Code:
Minimum PHP version required is 5.1.0. You are using PHP version 4.3.11
Does anyone, who has successfully installed SugarCRM on Yahoo! Web Hosting, know if there is a work around for this (besides using a different web hosting service)?
