Noob question on OpenGL glut compilation

Here I am again.

I got Xfree to work now, on the notebook. I just bought a book on OpenGL coding, but I cant get my code compliled.
I'm still new in linux so I trie to compile with the following line :

g++ -Wall -lGL -lGLU -lglut -o -simple.c

the errormessage is that he can't find lglut, but what is this lglut, where can I find it, and how do I make the compiler find it.

I did install the glut toolkit, complete with demo's, and development tools.
so I guess I just forgot to link something. If u know, please let me now, so I can run my first OpenGL rendered White Triangle (!!!).

Tnx allready, Greetz from the Netherlands, D1G1T4LL...
