It failed to depend on local vapis.  At least I understand it again.

The in-source dependency comments are there for the VIM Syntastic Vala plugin.
Vala just makes all sorts of things complicated but it's a necessary evil here.

# - Precompilation of Vala/Genie source files into C sources
# Makes use of the parallel build ability introduced in Vala 0.11. Derived
# from a similar module by Jakob Westhoff and the original GNU Make rules.
# Might be a bit oversimplified.
# Makes use of the parallel build ability introduced in Vala 0.11.
# Might be a bit oversimplified and inefficient but at least it's short.
# Filenames must be unique within a single compilation unit and that's fine.
#
# This module defines three functions. The first one:
#
# vala_init (id
# vala_precompile (source... - .vala, .gs, .vapi
# [DIRECTORY dir] - Output directory (binary dir by default)
# [PACKAGES package...] - Package dependencies
# [OPTIONS option...] - Extra valac options
# [CUSTOM_VAPIS file...]) - Custom vapi files to include in the build
#
# initializes a single precompilation unit using the given arguments.
# You can put files into it via the following function:
#
# vala_add (id source.vala
# [DEPENDS source...]) - Vala/Genie source or .vapi dependencies
#
# Finally retrieve paths for generated C files by calling:
#
# vala_finish (id
# [SOURCES sources_var] - Input Vala/Genie sources
# [OUTPUTS outputs_var] - Output C sources
# [GENERATE_HEADER id.h - Generate id.h and id_internal.h
# [GENERATE_VAPI id.vapi] - Generate a vapi file
# [GENERATE_SYMBOLS id.def]]) - Generate a list of public symbols
# [HEADER id.h - Generate id.h and id_internal.h
# [VAPI id.vapi] - Generate a vapi file
# [SYMBOLS id.def]]) - Generate a list of public symbols
