[Nel] driver_opengl linking: unresolved externals

[jay . bradley]

I'm having some difficulty pinning down why I am missing 3 unresolved externals 
for the driver_opengl linkage. I'm using Visual C++ and have followed the 
recent advice on DirectX 8. I presume I am missing a library or have the wrong 
version of a library. Can anyone advise me further?

Here is the linker output:
