@Flash, as interesting as it is, unfortunately it's not the same thing. The article talks about a completely different compiler (called Codon) that can understand a subset of Python. But they are not the same thing. Python users don't benefit from the speed improvement that Codon does.
@Neo_78 - the compilation only take a few minutes on my machine. Yours may vary.
Yeah, the documentation for Fatdog's pkgbuild system leaves a lot to be desired. It is currently very sparse. But we generally don't spend effort for things that have no demand. As it is, Fatdog's pkgbuild was released 9 years ago, and you are the first person ever who asks about it. If more people have asked, we might be more motivated to document it better ...
In the meanwhile, there is an example recipe file on /usr/src/pkgbuild/pkg/shell/recipe
. It generally explains the flow of the recipe, and options you can put in it. Fatdog pkgbuild system basically loads up the recipe, and calls up certain script functions you specify in the recipe, to build the package. For more examples, look up /usr/src/pkgbuild/source
. This folder contains the recipes of all packages you have installed in your system.
