Thanks, Jeremy! If you still have them, I would try them, but no 
guarantee I can finish this, because different techniques get different 
dependency lists, and Mathics people just say use Ubuntu to get 
dependency list for Slackware, which I don't think I'm going to do.  We 
need to find the correct technique to get the list for Slackware and 
separate required and optional ones... which I'm still unsure how to 
do.  Is it acceptable to SlackBuild with pip--maybe the Python ones have 
been updated to guide one with that?

After reading/discussion seems doable with fair bit of work... maybe a few hours/days after learning more.  Thing is, I've never really been a Python fan, so sounds easier to install gratis Mathematica on rpd or ARM to use with remote X Window System or some other remote access (with one of several/few SlackBuilds here for that).  If anyone actually uses Mathics and wants it updated but no one's interested, I can try more later, but more interested either changing Moria SlackBuild to colour Moria or adding unless anyone gets to it first, and testing LuckyCyborgs KDE6 to update KuickShow.

Yes, because '--dry-run' seem to not exist.
