Why copy bin/* and lib/*, instead of only the programs and libraries
needed. For example,
  $ cp /bin/ls ~ftp/bin
  $ ldd -d /bin/ls 
          libc.so.6 => /lib/libc.so.6 (0x40006000)
          /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)
  $ cp /lib/libc.so.6 /lib/ld-linux.so.2 ~ftp/lib
  $ # be paranoid
  $ ldd /lib/libc.so.6
          /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)
  $ ldd /lib/ld-linux.so.2
          statically linked
  $ # ok, so no need to be paranoid.

If there's any other programs that need to be copied, do basically the
same thing.
