[libvirt] How to install libvirt-python from source code?

Hi, I’d like to install a latest version libvirt on CentOS 6.5. I compiled libvirt, it worked well and then I tried to install libvirt-python. The version is libvirt-python-1.2.7, and I used `python setup.py build` and `sudo python setup.py install` to install. But in python, I get errors like: ========== Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib64/python2.6/site-packages/libvirt.py", line 28, in <module> raise lib_e ImportError: /usr/lib64/python2.6/site-packages/libvirtmod.so: undefined symbol: virTypedParamsAddBoolean ========== Someone would help?
