GEN WebKit-1.0.gir Couldn't find include 'Gtk-2.0.gir' (search path: ['./Source/WebKit/gtk', '.', '/usr/local/share/gir-1.0', '/usr/share/gir-1.0', '/usr/share/gir-1.0', '/usr/share/gir-1.0', '/usr/share/gir-1.0'])
also fails if introspection use flag is unset
(In reply to comment #1) > also fails if introspection use flag is unset No, that worked fine for me. If you have a problem with that you should file a new bug with information about how it fails there, not here.
Hum, don't know how this was missed. It needs gtk+[introspection] and libsoup[introspection]. Added to the ebuild, thanks for reporting!
