Please get into the habit of including the the compiler invocation
with bug reports like this -- otherwise we have to guess a lot.

1:  Can you verify that the package that you are trying to install is
    invoking a C++ compiler (like "g++") rather than mistakenly
    invoking something that looks a lot like a C++ compiler but is not
    (like "gcc").

2:  Can you verify that you have installed the C++ development
    libraries (whatever these are called) on your system?  On my
    Fedora box, these are in a package called libstdc++-devel.

3:  What happens when you try to compile the following program with
    your C++ compiler?  Please let us know:

         #include <iostream>
         #include <stdlib.h>

         int main() { 
            std::cout << "Hello World" << std::endl;

            return EXIT_SUCCESS;
         }

    I would suggest you compile this with "g++", but please tell us if
    you chose some other way to compile this.
