X11 with Open Office

[Hayden Smith]

Hi there,
I have a pre-configured macbook and I'm attempting to install X11 - as Open 
Office requires. As I am running OSX10.5, I would've assumed it was in my 
utilities folder which it isn't. Therefore, I attempted to install it from the 
optional installs which it was disabled. I then attempted to locate a recete 
which again, I could not locate. Does anyone know what my problem might be here 
- as the open office install is assured that it is not installed and yet I am 
unable to do so.
Cheers
