Have you made your modifications by hand?
Is much better to modify gtk-doc annotations[1] in order to generate correct
GIR files, this will help other languages as well like python, JavaScript
and other supporting GObjectIntrospection, including Vala. Or use a
Meta-3.0.metadata[2] in order to tell vapi generator to create correct vapi,
including header files to use[3].
I don't really know but Vala may is switching to GIR. Vala's compiler search
for GIR/TYPLIB when --pkg request a package like:
valac --pkg Meta-3.0 test.vala
will search on {prefix}/share/gir-1.0/ directory for Meta-3.0.gir package,
parse it automatically (including its dependencies) and them compiles. It
sends lot of CRITICAL messages on vala_gir_parser_* and other functions, but
they will be seen even when generating VAPI files, because they come from
Vala's GIR parser.
Take the last and search just Error messages on VAPI generation, they are
more useful than the CRITICAL ones.
