I am having the same issue. I have tried downgrading libstdc++ to the 'testing' version, but that didn't solve the issue.
Another program, aside from apt-get, that shows the issue is 'smartctl' from the 'smartmontools' package, which says: smartctl: symbol lookup error: /usr/lib/libstdc++.so.6: undefined symbol: _ZNSt8messagesIcE2idE, version GLIBCXX_3.4 -- by LjL ljl...@tiscali.it
