From `equery f libstdc++-v3`: * Contents of sys-libs/libstdc++-v3-3.3.4: /etc /etc/env.d /etc/env.d/99libstdc++ /usr /usr/lib64 /usr/lib64/libstdc++-v3 /usr/lib64/libstdc++-v3/libstdc++.so.5 -> libstdc++.so.5.0.6 /usr/lib64/libstdc++-v3/libstdc++.so.5.0.6 There is no lib32 version of libstdc++.so.5.0.6 installed. I have a multilib profile installed, and all the other necessary libraries are installing their 32 bit counterparts in /lib32; however libstdc++ is not. I checked on the ebuild, and it is definitely including the "MULTILIB_OSDIRNAMES" portion during the compliation as dictated by the 'has_multilib_profile' check, and the output of the compiler mentions multilib several times. However, it simply is not installing the libraries into lib32.

You can find the 32bit libraries in app-emulation/emul-linux-x86-compat. I'm not sure why we would want libstdc++-v3 to build for more than one ABI, but either way we should fix it or clean out the ebuild, so I'm leaving this bug open.
Perhaps I'm confused about the intentions of multilib, but my impression was that it should automatically compile the 32 bit versions as well as the 64 bit versions. The rest of the multilib enabled packages (eg: glibc) do this. The description of emul-linux-x86-compat is: "emul-linux-x86 version of lib-compat, with the addition of a 32bit libgcc_s and the libstdc++ versions provided by gcc 3.3 and 3.4 for non-multilib systems", specifically noting "for non-multilib systems". I feel like it is more consistent to change the libstdc++ ebuild to build a 32 bit version (since it seems to be documented for that to be the intention) instead of changing the documentation on the ebuild. If not, then what's the point of having multilib profiles?
well, libstdc++-v3 is not a multilib-enabled package. we'd do it this way if it wasn't such a hassle, i.e. if we had true multilib support. for the time being, we'll have to do with the emul-package
