I tried to build a new release of evolution into rawhide, but it fails with:

DEBUG util.py:264: Error: Package: gdk-pixbuf2-devel-2.29.0-1.fc20.i686 (build)[[BR]]
DEBUG util.py:264: Requires: pkgconfig(libpng15)

We had some talks about this with phracek, but there didn't change anything in koji with related packages (gdk-pixbuf2, libpng, libpng15), still I cannot build evolution. it started suddenly, I have failed builds, in build.log, which passed root.log without issues.

Evolution build (root.log passed successfully):
