Reviewer guidance

Set up a Python 2.7 virtualenv.
Run make staticdeps and make staticdeps-cext.

Set up a Python 3.11 virtualenv. Install kolibri and all dependencies into the virtualenv. Install PyOpenSSL version 23.0.0 into the virtual env.

Run kolibri, ensure that it does not give the error reported above (or any errors, hopefully!).
