That's the right environment variable, but I don't know why it isn't
working.  You can try either:

        0) printing the value of LD_LIBRARY_PATH from within the
           python script to make sure it is defined and has the right
           value.
        1) compiling the module statically (-static).
        2) copying libstdc++.so.5 into /usr/lib
