Default [HELP] libGL and libGLU not linked with the same libstdc...


I've ported a little demo of GLSL of a friend, and after having fixed all the compilation errors, i've got this last one:
creak@slibar:~/Desktop/pour creak/OpenGL/sources$ make
g++ -o ogl_test DataPack.cpp Main.cpp Object3D.cpp Object3DS.cpp ObjectMD5.cpp ogl.cpp Shader.cpp tga.cpp vector3f.cpp -lGL -lGLEW -lglut
/usr/bin/ld: warning: libstdc++.so.5, needed by /usr/bin/../lib/libGLU.so.1, may conflict with libstdc++.so.6
Then I've done an ldd on the binary:
creak@slibar:~/Desktop/pour creak/OpenGL/sources$ ldd ./ogl_test
        linux-gate.so.1 =>  (0xffffe000)
        libGL.so.1 => /usr/lib/libGL.so.1 (0xb7f64000)
        libGLEW.so.1.3 => /usr/lib/libGLEW.so.1.3 (0xb7f30000)
        libglut.so.3 => /usr/lib/libglut.so.3 (0xb7f07000)
        libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0xb7e21000)
        libm.so.6 => /lib/tls/libm.so.6 (0xb7dfb000)
        libgcc_s.so.1 => /lib/libgcc_s.so.1 (0xb7df0000)
        libc.so.6 => /lib/tls/libc.so.6 (0xb7cb8000)
        libGLU.so.1 => /usr/X11R6/lib/libGLU.so.1 (0xb7c3d000)
        libGLcore.so.1 => /usr/lib/libGLcore.so.1 (0xb74eb000)
        libnvidia-tls.so.1 => /usr/lib/tls/libnvidia-tls.so.1 (0xb74e9000)
        libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0xb74db000)
        libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0xb7410000)
        libdl.so.2 => /lib/tls/libdl.so.2 (0xb740c000)
        libXmu.so.6 => /usr/X11R6/lib/libXmu.so.6 (0xb73f7000)
        libXi.so.6 => /usr/X11R6/lib/libXi.so.6 (0xb73ee000)
        /lib/ld-linux.so.2 (0xb7feb000)
        libstdc++.so.5 => /usr/lib/libstdc++.so.5 (0xb7334000)
        libXt.so.6 => /usr/X11R6/lib/libXt.so.6 (0xb72e5000)
        libSM.so.6 => /usr/X11R6/lib/libSM.so.6 (0xb72dc000)
        libICE.so.6 => /usr/X11R6/lib/libICE.so.6 (0xb72c5000)
As you can see, both libstdc++.so.6 and .5 are linked... Certainly because of the warning above

Is the GLU library sent with the nVidia drivers? like the GL one...
I have the version 1.0-7174 of the nVidia drivers (i don't know why, they didn't get to the 1.0-7676 in the Debian repository)...

libGLU.so is not provided by Nvidia as it is a utility library build on top of OpenGL. Most distributions ship the libGLU.so from mesa.
