Thank you for clearing up what I suspected. In the chroot 64 bit 
installation an ldd /sbin/iptables shows
        libdl.so.2 => /lib/libdl.so.2 (0x0000002a9566c000)
        libnsl.so.1 => /lib/libnsl.so.1 (0x0000002a95770000)
        libc.so.6 => /lib/libc.so.6 (0x0000002a95886000)
        /lib64/ld-linux-x86-64.so.2 => /lib64/ld-linux-x86-64.so.2 
(0x0000002a95

The last library is easy to integrate into the 32 bit i386 sarge. But what 
about the first three ones. How can I make the 64 bit iptables binary 
which I put to /usr/local/sbin in 32 bit sarge look for the libs in 
another place but /lib where the 32 bit libs with the same name are 
placed ?
