I just started playing with the latest metatools (v1.0.2) and immediately hit this roadblock. After defining an autogen.yaml, I run `doit`, which immediately crashes with `ImportError: cannot import name 'soft_unicode' from 'markupsafe' (/usr/lib/python3.7/site-packages/markupsafe/_init_.py
)`. Following the stack trace, this follows from `import jinja2` in `/usr/lib/python3.7/subpop/org.funtoo.metatools/pkgtools/ebuild.py`.

This can by verified by e.g. running `python3 -c "import jinja2"`. There's a bunch of reported errors against jinja2 e.g. https://github.com/pallets/jinja/issues/1599. I think I have the latest jinja (v3.1.1) and markupsafe(v2.1.1) installed so it should all work. I'm not sure why I'm seeing this incompatibility.
