The log says:

:info:build /usr/local/include/opencv2/contrib/contrib.hpp:273:23: error: no template named 'vector'; did you mean 'std::vector'?
:info:build         Octree( const vector<Point3f>& points, int maxLevels = 10, int minPoints = 20 );
:info:build                       ^

This means you have a copy of opencv installed in /usr/local. We don't support installing software in /usr/local while using MacPorts, because of the likelihood of these kinds of conflicts. Please remove what you have installed in /usr/local.

Even after doing so, digikam won't build, however; we're tracking that problem in #48081. We need to update digikam to a newer version; an update is proposed in #47772.
