I'm building a minimal Gentoo system but I always get the following error when I try to chroot into the final system:

/bin/bash: error while loading shared libraries: libgcc_s.so.1: cannot open shared object file: No such file or directory

I ran 'equery b /usr/lib64/gcc/x86_64-pc-linux-gnu/4.5.4/libgcc_s.so.1' on one of my conventionally-built Gentoo systems and the file isn't determined to belong to any package.

Where does this file come from and how can I add it to my manually-built Gentoo system?

I'm following these instructions to build the minimal Gentoo system:
