You can't check with strings. The right way to check the version
information is by using  'objdump -p' on the library. When doing so,
you'll see something like

Version definitions:
1 0x01 0x025f4d66 libstdc++.so.6
2 0x00 0x08922974 GLIBCXX_3.4
3 0x00 0x02297f81 GLIBCXX_3.4.1
        GLIBCXX_3.4
4 0x00 0x02297f82 GLIBCXX_3.4.2
        GLIBCXX_3.4.1
5 0x00 0x02297f83 GLIBCXX_3.4.3
        GLIBCXX_3.4.2

Looks likeWhat ldconfig is telling you is that it doesn't find the
library. Try calling ldconfig to get the dynamic linker to cache the
library and then again ldd.

I'm certain that is does contain the info when looking with the right
tool :)
