No vapigen-0.16.pc file is installed

[esodan]

Installing libvala-0.16-dev just install /usr/lib/x86_64-linux-gnu/pkgconfig/libvala-0.16.pc file but not vapigen-0.16.pc

This file is required when generating VAPI files form C sources. M4 macro from Vala git repository checks for 'vapigen' package, this macro is 'recommended' to be used by all software supporting VAPI integration but must be installed vapigen-0.16.pc file first.

I can't fix GNOME bug #678647 because I want to port LIBGDA to this new VAPIGEN's integration.
