Do you have python-ctypes installed?
Besides iotop does not work for kernels < 2.6.20. You need a patched kernel. The rpm package from http://guichaz.free.fr/iotop/ works also on non standard el5 kernels but shows no more information than iostat.
thats not true. the EL kernels have block dev accounting backported in, use the iotop from EPEL, and use a recent'ish kernel for CentOS-5, and you should be fine.
