It's really just a matter of going through the dependencies listed in the
now pyproject.toml, try building, and see if it complains. Once all the
complaints are resolved and it builds, install it, and use `pip check` to
see what else is missing that it's asking for. Install those, and then try
running the program to see if it complains again. Then just make sure the
dependencies are documented in the .info file.

I had some free time this evening, so I tried my hand at this. I created a
SlackBuild for mathics-core (using my SlackBuild generator script
<https://github.com/bassmadrigal/scripts/blob/master/sbgen.sh> --
*shameless plug*). After running that, I removed the setup.py entries (from
the template) and ran the script. It complained about setuptools being too
old and missing mathics-scanner. So I added a dependency to mathics-scanner
and python3-setuptools-opt and added the command in the script to update
the python path for the newer setuptools.

Then I created a script for mathics-scanner using the same slackbuild
generator script and went through the same process as I previously did.
Once mathics-scanner compiled, I went back to mathics-core and went through
that process futher.

Ultimately, I found that mathics-core requires a few packages not on SBo
yet (palettable, pint, & pympler, which I've listed with "@" around them in
the mathics-core.info) and it complained about an outdated pillow version.
For testing, I installed them using pip (in an otherwise clean environment
that I can reset easily to not have python modules installed via pip in
normal operation), and was able to finally start up mathics without error.
However, I know absolutely nothing about mathics and don't know what to run
to check if it's working properly. I have no idea if having an outdated
version of pillow (stock 15.0 package) will cause any issues with output,
so that would certainly need to be tested further.

I made a zip file of these two SlackBuilds and attached it (if it isn't
blocked) and put it on my server
<http://bassmadrigal.duckdns.org/mathics.tar.gz> (for at least a few weeks
until I go through and purge unneeded files in there) if you're interested
in creating SlackBuilds for pint and palettable and can otherwise test if
mathics works once those dependencies are met. I won't be willing to
maintain these SlackBuilds since I don't use mathics and wouldn't know how
to test it, so feel free to take over if you (or someone else) is
interested in continuing it.

If you have any questions, I'll try to answer them the best I can.
