I fixed the digikam failure to build. Same type of patch was needed as for gwenview
(replace all instances of JTQT_METHOD with JMETHOD.).
Patch:
http://humanreadable.nfshost.com/trinity/patches/digikam/digikam-3.5.13-jpe…
Somebody please merge the patch to svn/git/whatever.
Anybody building digikam 3.5.13 will need the patch.
