Install python-gphoto2 on Raspberry Pi/Raspbian Wheezy - success

Refer to the previous post "Install and test python-gphoto2 (Python interface to libgphoto2) on Raspberry Pi 2/Raspbian Jessie", success to install but fail to run. In order to verify the steps, I redo it on Raspberry Pi (1st generation, NOT 2)/Raspbian Wheezy.

Install gphoto2 and libgphoto using gphoto2-updater script. Both gphoto2 and libgphoto2 installed are version 2.5.8.

Then install python-gphoto2:
$ sudo apt-get install python-pip
$ sudo apt-get install python-dev
$ sudo pip install gphoto2

It seem much better.
