I got past the previous error. I needed a libpng14 patch (http://humanreadable.nfshost.com/trinity/patches/digikam/0.9.6-libpng-1.4.pa...).
Digikam still fails to build.
New log:
http://humanreadable.nfshost.com/trinity/build_logs/digikam-3.5.13-i486-1-bu...
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-jpeg...
Somebody please merge the patch to svn/git/whatever.
Anybody building digikam 3.5.13 will need the patch.
