python 2.6 - No module named _cffi_backend

Question

I have python2.6 in my Linux rhel-5. I have installed pip and required CFFI packages. When i try to run a sample CFFI program it says :

ffi = FFI()

File "/usr/lib/python2.6/site-packages/cffi/api.py", line 56, in init

import _cffi_backend as backend

ImportError: No module named _cffi_backend

what could be the posiible error. Did i miss something during install. i have installed pip, wheel, pycparser, pytest, cffi....
