The answer may be to run "kbuildsycoca4" from the command line (full
path /opt/local/bin/kbuildsycoca4).  This is a KDE utility that maintains
a cache of KDE applications and where to find them (sycoca = system
configuration cache).

It is a good idea to run this after installing any KDE app in Macports.  For
more information, there was a thread on this list entitled "SyCoCa - Fixing
broken KDE apps", from 16 Sept 2012 to 8 Oct 2012.

Basically, the larger KDE apps, such as Digikam, tend to rely on other
apps, plugins or KParts for some of their functionality and KSyCoCa4
tells the apps where to find other components and how to launch them.

Hope this helps.  I am glad you can get Digikam to install - I must have
another go sometime ...
