ldd shows you which library files that ls depends on. You should see 
something like this:

westk[@westek]:/home/westk:> ldd /bin/ls
       linux-gate.so.1 =>  (0xffffe000)
       librt.so.1 => /lib/tls/librt.so.1 (0xb7fd0000)
       libacl.so.1 => /lib/libacl.so.1 (0xb7fc8000)
       libselinux.so.1 => /lib/libselinux.so.1 (0xb7fb5000)
       libc.so.6 => /lib/tls/libc.so.6 (0xb7e7d000)
       libpthread.so.0 => /lib/tls/libpthread.so.0 (0xb7e6b000)
       /lib/ld-linux.so.2 (0xb7fea000)
       libattr.so.1 => /lib/libattr.so.1 (0xb7e66000)
       libdl.so.2 => /lib/tls/libdl.so.2 (0xb7e62000)
       libsepol.so.1 => /lib/libsepol.so.1 (0xb7e28000)


If one of the files says something can't be found, like this:
westk[@westek]:/home/westk:> ldd /bin/ls
       linux-gate.so.1 =>  (0xffffe000)
       librt.so.1 => /lib/tls/librt.so.1 (0xb7fd0000)
       libacl.so.1 => /lib/libacl.so.1 (0xb7fc8000)
       libselinux.so.1 => /lib/libselinux.so.1 (0xb7fb5000)
       libc.so.6 => /lib/tls/libc.so.6 (0xb7e7d000)
       libpthread.so.0 => /lib/tls/libpthread.so.0 (0xb7e6b000)
       /lib/ld-linux.so.2 (0xb7fea000)
       libattr.so.1 => /lib/libattr.so.1 (0xb7e66000)
       libdl.so.2 => /lib/tls/libdl.so.2 (0xb7e62000)
       libsepol.so.1 => not found

that's the clue you need to start fixing the problem.
