Then I think what's happening is that the new GCC you've built depends on the shared libraries in $PREFIX/lib64 but the dynamic loader can't find those libraries. If you set LD_LIBRARY_PATH=$PREFIX/lib64 in your environment that should allow you to build, but it might be better to just ensure you don't use $PREFIX/bin/g++ for the build.
