Compilation error with freeglut

[A K Arun]

Hi,
I'm quite new to linux and am facing a few problems while compiling a
program in C which uses OpenGL. I have installed Red Hat Enterprise Linux 5
and freeglut was installed as part of the linux installation.

make: *** [ps3.o] Error 1


Please find attached 'sample.tar.gz'. It contains the following-
- C program which I'm trying to compile
- Makefile
- header file

Have I missed a step or two after the installation ? Something like
configuring the path etc. If so then please let me know of the same.
Any idea on which header file to use in case of freeglut ? Is it freeglut.h
? Though I couldn't find it on my linux box.
