Thanks Doug and Jerome,
I loaded Python-opencv and then did "apt-get install", which said I had
the latest file.
"Loaded plugins" says "Failed.......No module named cv"
All I have is, on media page, Bottom bar, is a new tab "Faces" in bold.
I had a bit of spare time and was looking for new "Goodies" I have yet
to discovery in Gramps.
So if its in its early stages, I am not worried about it.
Just to thank every one for all their hard work on it.
