Ceph

I. How to reproduce:
1. Clone the latest ceph master code from github

2. From my laptop, install the pre-requirement packages, build the source code with "./configure --without-tcmalloc " and install ceph.

3. Try "ceph -v" to check if ceph is successfully installed, and error occurred as below, while 'rbd -v', 'rados -v', 'ceph-fuse -v' are all works as expected.

The detail info is:
[houming@localhost ~]$ ceph -v
Traceback (most recent call last):
File "/usr/local/bin/ceph", line 56, in <module>
import rados
ImportError: No module named rados
