 you also need at least /lib and probably /usr/lib. On my Debian system,
 even bash is dynamically linked:

 $ ldd /bin/bash
         linux-gate.so.1 =>  (0xffffe000)
         libncurses.so.5 => /lib/libncurses.so.5 (0xb7f26000)
         libdl.so.2 => /lib/tls/libdl.so.2 (0xb7f22000)
         libc.so.6 => /lib/tls/libc.so.6 (0xb7dea000)
         /lib/ld-linux.so.2 (0xb7f82000)

There is a separate "sash" package which includes a statically-linked
shell, but it's not a default.
