It means that your C++ compiler is not setup right.   IIRC, libstdc++ 5
is used by GCC 3.2, and the older libstdc++ 3 is used by GCC 2.95.  You
said before that you are using 2.96, which I assume is the same thing. 
There should be one and only one symbolic link from libstdc++.so to
whatever library is appropriate for the compiler you want to use. 
Either rebuild Visual with GCC 3.2 or fix your link and then rebuild
visual with GCC 2.96.
