The relevant part out of the huge pastebin is:

Which means that your PIL (Pillow) library in
build/bdist.freebsd-11.0-RELEASE-p2-amd64/egg/PIL is still not capable to load
jpeg files. This is indeed a Python/FreeBSD specific problem, not a Plone one.
My FreeBSD knowledge is a bit aged (last time I used it >12years ago). I would say there was some problem while building the package from the sources.
Specifically PIL/Pillow contains only the features where it has libraries available at build/compile time. It do not complain if a feature is missing, but then you can not load the file type.
You may ask at Pillow or FreeBSD forums/mailing lists for more specific information unless someone with more knowledge pops up here.
