Hi Angelo,

thx for libkexiv2 0.1.5  with libkexiv2.so.1.   Now digikam can still use 0.1.1
with libkexiv2.so.0.

I've tried rebuilding digikam 0.9.1 with likexiv2 0.1.5 and this also works fine.

At least in kubuntu only digikam and digikamimageplugins depend on libkexiv2
and those two are merged in 0.9.1.  PUh, that's easy ;)
