run a 32bit program on a 64bit gentoo linux

I am having difficulties running 32bit code on my 64bit gentoo, the program is very simple:

#include <stdio.h>

main()
{
        printf("Hello World");    
}

I compiled it with gcc -m32 -o hello32 hello.c. The output seems correct:

ozn@yeni2gen:~$ gcc -m32 -o hello32 hello.c
ozn@yeni2gen:~$ file hello32 
hello32: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, for GNU/Linux 2.6.32, not stripped

But when I try to run the file I get an error:

./hello32 
bash: ./hello32: No such file or directory

OK, thanks for the hints. Apparently, I am doing something wrong with my gentoo. After digging a lot in the gentoo forums, and thanks for the hints here, I found a solution:

(root)# ln -vs /lib32/ld-linux.so.2 /lib/ld-linux.so.2

The original discussion in the gentoo forums which gave me this hint.
