It should be --pkg gee-0.8 It is case sensitive!
You also need the development files installed. For Ubuntu that would be something likeapt install libgee-dev

> GIR files:
You want to avoid GIR files to start with. They are GObject Introspection Repository (GIR)files that contain 
enough information about a C library's interface to generate bindings forvarious languages, including Vala. 
The Vala tool vapigen can then be used to generate aVala Application Programming Interface (VAPI) file from 
the GIR. valac can do this automaticallyif a VAPI is not found.
By using the capitalized version, --pkg Gee-0.8, valac tried to generate the VAPI for you by
searching for the relevant GIR. It looks like that wasn't found either, probably because youdon't have the 
development files installed. If you look at the files in the dev package youshould see the difference in 
filenames.

When starting out you want to focus on using VAPI files for interfacing with libraries.
All the best,
