libstdc++6-dev 3.4.6-2 (amd64 binary) in ubuntu edgy

 This package contains the headers and static library files necessary for
 building C++ programs which use libstdc++. Be advised that this only works
 with the GNU C++ compiler (version 3.0), and no earlier library will work it.
 .
 libstdc++-v3 is a complete rewrite from the previous libstdc++-v2, which
 was included up to g++-2.95. The first version of libstdc++-v3 appeared
 in g++-3.0.
