Unable to compile OpenGL/C program

[Arvind S Raj]

Hello everyone,
I had visited #opengl on freenode yesterday and they seemed to be stumped
about the issue too so thought I'd ask here as well.

I'm running Kubuntu 11.04 64bit and have installed the packages
libgl1-mesa-dev, libglu1-mesa-dev and freeglut3-dev.

I'm trying to compile the following program -> http://pastebin.com/PhiLayVQ.

and these are the errors I get. I'm guessing the libraries can't be found or
something?

$ alias glc
alias glc='gcc -lm -lglut -lGL -lGLU'
$ glc 1_basic.c
/tmp/ccN3AU7G.o: In function `main':
1_basic.c:(.text+0x1e): undefined reference to `glutInit'

collect2: ld returned 1 exit status

I've been unable to find out what is wrong. It'll be great if I can get some
help regarding this.
