The path usr/local/lib/../lib/libstdc++.so makes me think that you (or someone else) installed GCC from sources.
Yes, you are right. I built the release 4.3.3 also myself.
Please check using file(1).

Can you actually compile and link any C++ program with that compiler? A test with an "hello world" program should suffice.
Yes - The following example works as expected.
#include <iostream> int main(void) { std::cout << "Test" << std::endl; return 0; }
elfring@Sonne:~/Projekte/GNU/GCC> /usr/local/bin/g++ Test.cpp && ./a.out Test
The compiler software passed the usual test cases (make check) on my system, too.
