I've finally succeeded in setting up my environment for building and
contributing packages. Thanks for making it clear that `make` is needed.
This is certainly not explicitly mentioned in the docs as far as I can

Well I guess that wouldn't have mattered that much if there was a known
way to run `make` only for the packages and not for the whole code base
which is huge.

I'm not sure. The problem for me was that I ran `make clean` under the
source tree and then I couldn't figure out why packages weren't loaded
anymore from my tree. I still don't understand really why these scheme
files aren't loaded dynamically. Do I need these `.go` files to exist?
