Hi Austin,

Thanks for your help, I've sorted it now by installing some additional 
packages:

Glide3
Glide3-devel
XFree86-Mesa-libGL
XFree86-devel
XFree86-libs
XFree86-libs-data

I'm short on time so didn't narrow it down any further, but one of the above
allowed me to achieve the desired outcome.

Thanks again,
Andrew
