[ubuntu] Python upgrade offline

Hello. I have desktop pc running Ubuntu 10.04, without internet connection and want to upgrade python on it. I downloaded sources on another pc, configured, installed, it shows me python 2.7 binaries, upgraded 2.6 as well from 2.6.5 to 2.6.8, but when i try installing wicd-gtk it says that my python version is 2.6.5. Any idea how to make it see changes?

Thanks in advice,
Dracco
