Pascal,

Python 3 > 3.2 is mandatory, it's required for both meson and GObject-Introspection. 

All of those folders with all-caps names (DEVPREFIX etc) shouldn't exist. Those are supposed to be 
environment variables, not folders. Did you create them manually or did the script do that?

`jhbuild bootstrap` requires replacing the bootstrap.modules distributed with jhbuild with the gtk-osx ones. 
It's a process I inherited when I took over gtk-osx from Richard Hult 10 years ago and I've never liked it. 
Building meta-bootstrap from the gtk-osx modules explicitly avoids dirtying the jhbuild repo.

I think you'll have to do a two-stage build for your python2 project: Build everything that needs to be 
introspected using the virtenv's python3 as python, then build python2 and whatever pure-python projects so 
that you have the right environment for your program.
