Missing header GLTK in compiling an openGL program


I've recently started learning openGL programming. However, when I compile the program, it can't detect the header file "gltk.h", causing numerous functions not to be found. I have looked for a library containing these files, but the closest I got was a site with broken links claiming it had an rpm that probably didn't work. Either way, I'm at a loss. I'm sure there's something simple that I'm just not seeing, so I'm asking if anyone could point me in the right directon. As a note, I'm using Slackware 10.2 and kernel 2.6.14.4. I have also included the error message just in case I have a completely wrong idea of what's going on.


I am using the exact code from the following tutorial site:

http://www.eecs.tulane.edu/www/Terry...L%20Primitives

Code:
user@computer:~$ gcc -o Primitives Primitives.c -lX11 -lMesaGL -lMesaGLU -lMesatk -lm

that tutorial is using the Tk toolkit .. so you should have somthing specific for Tk and opengl, probably from the website? ..

I have never used Tk and opengl, or Tk for that matter.. i have however used alot of the tutorials at NeHe's site and have not had any problems..
