Can you tell me what running pip freeze |grep gphoto returns for you?

I changed the module name from gphoto2 to gphoto2cffi in the latest gphoto2-cffi alpha release. However, this is not yet published on PyPi, so as long as you didn't install gphoto2-cffi from a source checkout you shouldn't run into this problem....

I did install gphoto2-cffi from source.

[jbaiter]

There you go, please stick to the version on PyPi (i.e. pip install gphoto2-cffi) for now. There are no significant changes from 0.2 to 0.3 that affect the driver behavior, so it's not really worth the upgrade.
