g++4.7 error: libstdc++.so.6 version GLIBCXX_3.4.15 not found

[neilms]

I installed gcc 4.7. When I attempt to compile a c++11 program,
I get this error:
/usr/lib/libstdc++.so.6 version GLIBCXX_3.4.15 not found.
Do you have any ideas how to fix this? Come on guys, we have to work the problem just like NASA do.
