[Vala] Package `Gee-0.8' not found

[Ralf Ganswindt <ralfganswindt gmail com>]

I'm experimenting with Vala and so far I like how it works. However, I
tried to compile a basic gee example from the sample programs and I get the
following:

$ valac --pkg Gee-0.8 list.vala
error: Package `Gee-0.8' not found in specified Vala API directories or
GObject-Introspection GIR directories
Compilation failed: 1 error(s), 0 warning(s)

A search of /usr/... reveals no gir or vapi files for Gee-0.8, only
gir1.2-gee-0.8 and libgee-0.8 related files and binaries.

I have attempted to manually install the files using the synaptic package
manager and it didn't throw any exceptions.

$ apt show -a gir1.2-gee-0.8

GIR files:

$ ls -R /usr/share/gir*

What am I missing? Before I try to back engineer myself into a disaster.
