Comment(by nicos_pavlov@…):

 Two components caused problems at compilation: kgamma and snapshot, but
 which are not breaking any dependency to my knowledge.

 Digikam is not resolved at this point, essentially because its variants
 depend also on kdeedu4 port, which was also fragmented.

 Finally, a proposition of meta-port kdegraphics4-meta, which could act as
 a replacement for kdegraphics4, by listing all dependencies previously
 being contained in kdegraphics 4.6 (apart from the ones not compiling at
 this stage).
