I tried to configure with the current gtk+-3.0 branch. waf still fails, this time only at gdl-1.0 check. When symlinking gdl-3.0.pc to gdl-1.0.pc and trying to ./waf, the build will still fail with error message:
error: Package `libvala-0.12' not found in specified Vala API directories or GObject-Introspection GIR directories
./waf configure found libvala-0.12 though and it is installed beside version 0.14.
I added blank lines in attachment for better view.
