Well it looks like user error was to blame for my
compile problems.

After a couple of hours of searching, I was able to
compile using the following:
gcc example.c -o example -lglu32 -lopengl32 -lglut

Now, my attempt to execute the program has hit a snag,
I'm seeing the following error:

-bash:example.exe: command not found.

(example.exe is definately in the directory)
