linker errors for OpenGL functions

[Graham Menhennitt]

G'day all,

I've screwed up something on my system. When I try to build the 
x11/kde4-workspace port, I get a pile of linker errors. I'm guessing 
that I just need to reinstall some other OpenGL port, but I can't find 
out which one. Any clues, please?

Thanks,

     Graham
