As reported on IRC, the
	views_stack.set_current_page (2);
line in contacts-avatar-dialog.vala aborts the build when building with --with-cheese, because GtkStack doesn’t have a set_current_page() method. That means the 3.13.90 tarball is broken --with-cheese.

Even if this is fixed, it exposes a fundamental problem with the use of Vala #if conditionals in the code — they aren’t propagated to the generated C code, so if a tarball is generated with --with-cheese, someone can’t then configure it --without-cheese and compile the C code from the tarball without re-running valac, which somewhat undermines the point of shipping generated C code in the tarball.

One suggested solution is to have two separate .vala files for the --with-cheese code and the --without-cheese code (there’s probably a nice way of separating it out to eliminate duplication), and to always generate C code from both. The --with[out]-cheese configure option would then affect which C file is compiled and which object file is linked into the gnome-contacts binary — rather than which .vala file is compiled in the first place.

That’s what libfolks does for its Zeitgeist support: https://git.gnome.org/browse/folks/tree/backends/telepathy/lib/Makefile.am#n80
