I compiled Opengl by installing the folowing packages through Synaptics Package manager.
freeglut3 freeglut3-dev freeglut3-dbg libglew1.5 libglew1.5-dev libglu1-mesa libglu1-mesa-dev libgl1-mesa-glx libgl1-mesa-dev
This is the output when I run the program.
X Error of failed request: GLXBadFBConfig
Major opcode of failed request: 156 (GLX)
Minor opcode of failed request: 34 ()
Serial number of failed request: 42
Current serial number in output stream: 41
The input to this
(lspci | grep VGA) ; \
(dpkg -l | egrep 'xorg-video|glx') ; \
(ls -l /usr/lib/xorg/modules/{drivers,extensions})
gives an output to this

The error code GLXBadFBConfig means that the system's display system (X11 server + graphics drivers) does not support the pixel format requested for by your program. This can happen if there are no drivers with OpenGL support installed, or if the requested FBConfig goes beyond the capabilities of the GPU.
Now that you posted the code it's easy to see where the problem is: Your system uses the open source radeon drivers of the Xorg/DRI/Mesa project. Those driver support only up to OpenGL-3.3 (this is also reported by glxinfo):
OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.1.0
However your program asks for a OpenGL-4.3 context
glutInitContextVersion(4, 3);
glutInitContextProfile(GLUT_CORE_PROFILE);
This is a request that your system can not satisfy. Hence you're not getting the desired FBConfig.
Note that so far your program uses only functions that are also available in OpenGL-3.3 so I suggest you simply ask for a 3.3 context in your program.
In your case I'd wager it's the first case: Your system lacks a proper driver installation.
To further help you, please add the output of the following commands to your question:
(lspci | grep VGA) ; \
(dpkg -l | egrep 'xorg-video|glx') ; \
(ls -l /usr/lib/xorg/modules/{drivers,extensions})
