Params:
- Linux solar 3.1.6-gentoo #16 SMP Thu Jan 5 14:49:10 GMT 2012 x86_64 AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ AuthenticAMD GNU/Linux
- gcc (Gentoo 4.5.3-r1 p1.0, pie-0.4.5) 4.5.3

Problem:
When I run applicaton it give me this error:
error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory


Solution:
> emerge app-emulation/emul-linux-x86-compat -av
It will install also sys-libs/libstdc++-v3
Also, may be you need to create a symbolic link in your application to this shared library.
