Thank you Justus for your advice, I could fix that and use the lib
from Python. I had not realized that both gpg and gpg2 are installed
by default on Ubuntu 16.04 LTS.

Do you know if there is any plan to better document the python
bindings in the GPGME doc? I may be able to help with that if needed.

Cheers,
Jean-François
