Hi, Well you have to do what the message says. Clearly, your X11 Header Files are missing. You will have to pick up your FC5 CD/DVD, and install the Header Files. If you run the Package Installer or Update Manager, you will have to go into the Development / Library section of packages, find X11 related packages / headers and install them. Once the headers are installed, the installation should (hopefully) run smoothly !!
Good Luck !!
