[Digikam-users] Too slow metadata writing with exiv2 and Nikon - how to solve?

[Emil Persson]

Ok. How do I update exiv2 the best way since many other programs depend on
it?
Through KPackageKit I don't see how.
If i download it and compile and install it I get 2 versions, not?
Could you Gilles, or some other friendly soul be more verbose? Or direct me
to a
tutorial that explains the process.
