digikam installation failed

[juer_gen01@…]

I tried several times to install digikam. + I uninstalled and cleaned it one try: I uninstalled "all" .. failed - searching similar tickets I found #29223 --> but "sudo port sync" did not fix the problem either: ok, I got some updates, but finally the installation failed again:
