No, this one was with opengl enabled, which was failing in do_configure do to missing gperf-native, but now when that was fixed it fails in do_compile.
Build without opengl still works with works with my patch.
I can no longer see the issue the patch was supposed to be fixing :-/ Maybe I had a broken build tree at some point. The patch can probably be dropped, but I need to run it on the AB to be sure.
What does 'bitbake-getvar -r webkitgtk PACKAGECONFIG' say on your side? I wonder what combination of options triggers your issue.
